in an effort to prevent expensive shutdowns and unplanned maintenance downtimes facilities across the globe today rely on a variety of preventive maintenance methods many studies indicate the temperature rise otherwise known as hot spots is a major cause for these failures these abnormalities are often caused by loose connections as a result of vibrations unbalanced loads overloaded conditions and a wide range of other issues often found in conductive environments most industries use either routine physical inspections or thermography programs to detect temperature abnormalities physical inspections require the user to open the electrical enclosure barriers and other insulating materials in order to inspect the connections since most facilities prohibit their personnel from this type of high risk access the data obtained is often inaccurate or unobtainable additional risk of failure exists when the equipment is not put back in the original condition after inspections to overcome these shortfalls and to measure the temperature of the live conductors some facilities use infrared cameras and windows with this method an IR camera is directed at a live conductor either directly or through an IR window to measure the rise in temperature in some cases the IR camera or the window visibility is restricted by the connection location and field of view of the IR window to help you address these concerns effectively we'd like to introduce our new grace sense hot spot monitor or HSM a continuous real-time temperature monitoring device intended for locations that are difficult at hazardous to access this device not only measures the temperature at any given point in time but also proactively monitors and enables the user to predict the failure before a potential shutdown the HSM utilizes patented fiber-optic technology providing constant temperature data available in 9 or 18 independent sources the fiber probes can be mounted onto electrical bus bars bus ducts transformers or any other source of heat the hotspot monitor provides a unique combination of patented fiber technology at advanced algorithms that convert the change in light intensity to temperature the patented fiber probes securely connect to a ring style connector that conveniently mounts to the source of heat while the other end connects to the HSM module sources of heat may include inaccessible equipment and blind spots to IR scanning the most obvious benefits of the HSM over IR thermography come from the continuous real-time monitoring feature in addition the successfully proven measurement accuracy of the probes is not subject to calibration errors as can be the case with IR scans the hotspot monitor comes with 16 megabytes of built-in memory for data storage by connecting the grace sense HSM module via Modbus tcp/ip or Ethernet IP and accessing the web utility tool users can configure the temperature thresholds time intervals and relay outputs this tool further enables access to the real-time data logs and downloads the stored data for analysis and trending connecting directly to the device or safely through closed doors using a grey sport Ethernet connector interface gray sense hotspot monitor is a reliable and affordable solution for use in environments with low medium or high voltage systems the HSM is available in two versions either a nine-point module with a built in LCD display or an 18-point module the unit comes fully kitted with fiber probes ring style connectors and an installation kit optional accessories include a Modbus current sensor high temperature probes ambient measurement attachment custom connectors and fiber lengths of various sizes continuous real-time monitoring our answer to your most demanding and critical applications where guesswork in downtime is not an option to learn more about our hot spot monitor visit gray sense.com or call 800 to 8:09 five one seven find faults before they find you so the topic for today is NFPA 70e sleep-related maintenance requirements for electrical equipment morning my name is Bonnie Srila as most of you know I'm the director of technical or product marketing here trace engineered products I've been with trace for about five years now and I'm not going to read through all my credentials right now this funnel know more about me just google my name or find me on my LinkedIn page so the topic outline for today is a routine so general maintenance requirements of electrical equipment as it applies gen of BS 70 II and a basic guidelines for a substation equipment MCC is panel boards circuit breakers disconnect switches and also that PPE so this is more so in alignment with what the chapter 2 which is article 200 parts about NFPA 70e and also learn how often the scheduled maintenance has to be performed on those equipment as well so we're going to touch base on two things here one is NFPA 70e standards one is the ANSI meter 2019 Edition which is the recommended practice for electrical equipment maintenance and also going to attach slightly on NFPA 70 B as well okay so let's take a quick fact check on the maintenance so what is the basic reason when we ask for the facilities personal about why do they perform maintenance tasks right the first thing that comes into mind is equipment shut down so people who don't perform any kind of a maintenance task unless otherwise there is something that's broken right so this more like a reactive approach what we do and then the second step is whenever there is a physical science of imminent failure like if you see a hot spot that if there is a or king or a flashover inside the cabinet that you visually can say it or you can see any kind of a temperature rise on the equipment then you send someone to go and perform the task right and last two things are like a pretty common I do this maintenance because my boss asked me to do this or have the procedures or policies in place which would demand me to do the task right and lastly I just do it for checkbox for the record so most people don't I know why they're doing the maintenance because maintenance also required by Occupational Safety and Health Administration Star Code of Federal Regulations which most people think that hey I need to just put a checkbox on those maintenance sheets or the records to make sure that I'm complying to those requirements that's on the reason why the people doing okay so in reality why do you need to be really really doing the maintenance right the first thing is support the facility operations and production you need to make sure the equipment is running its optimal level and you are producing the desired outcome of your equipment in the production capability and the second one is ensure the equipment performance to design spec so what I meant the design spec I'm talking about the equipment not performing at a forty percent efficiency or a 50 percent efficiency not shooting for 90 or 95 percent efficiencies toward the equipment has been designed to you and then the last next bullets are awarded unplanned downtime so you don't want the second point to just to go down on its own clock so you just want to make sure that the system shuts down based on the planned outage right and then they extend the equipment launch maybe most of the times the equipment is designed for twenty to thirty years in normal situations and in some key in some cases it's designed also for forty to fifty years I mean we come across most facilities where the hardest equipment for forty to fifty years one thing is they are maintained they could maintain sure they're getting the desired longevity of the equipment as well and the next bullet is the lower total cost of ownership it is not just the maintenance is a function of on a regular basis you go and perform a task it's also the design feature as well right so you look at the total cost of ownership you are taking to consideration the design standards the installation cost and also the cost of maintenance which gives you the complete aggregate of the total cost of ownership and the last two bullets are very important because one on a previous slide with cash which is complying with the regulatory needs because as I mentioned you occupational safety and health administration has a clear directive on what it means when it comes to the maintenance of the equipment and also the hazards as the delayed because of the maintenance of the equipment that leads to any kind of hazards there workers with employees and laster's keep personal safety so you need to make sure that you're doing all this maintenance tasks be ensured that the people who are working around the equipment I'm talking about two levels of well employees here one is the person who is doing the maintenance tasks and the second one is the one who is doing the operation right like a machine operator is also considered as a person who is involved with that operation as well okay so when it comes to the electrical work environment this is a three standards as I'm showing you on the screen installation maintenance and safe work practices come into play so you can't accomplish safer practices without the use of installation and maintenance these three things are tightly interrelated meaning you need to make sure the equipment is designed and installed or they quite codes and regulations right and then you also need to maintain the equipment ensure it's safe for the people to work around those devices and the last one is safe work practices which is more so in terms of the personal safety so if you look at the FPA 70 alone LF PA 70 calls out in specific areas there is a call out cannot be a 70 B which is a maintenance standard for recommended practice for electrical equipment maintenance and also the installation codes which is enough be a 70 or NEC okay so what is the role of maintenance condition condition of maintenance play a major role when it comes to safety because as I mentioned the previous slide it includes two types of workers one is the maintenance worker who is performing the tasks or the maintenance or repair functions around the equipment and then the next one is the operator so improperly maintained equipment can put both the maintenance worker and operator at risk when I say the operator and maintenance worker so I'm talking about the maintenance worker who's doing surgical tasks or mechanical tasks or like lockout tagout or the person who is doing the production activities on that specific equipment and last but not least there is also a significant role of the owner or the operator because when I'm going to talk about the maintenance in terms of occupational safety and health administration which we'll see in the next slides talk about that a possibility of the employer and the employee as well let's go to the next slide so this slide I'm applying one chapter 2 talks about specifically on the safety related maintenance departments and who is responsible for the other specific areas right so when it comes to the equipment it's not only the employee who is working around the equipment is responsible but ultimately the prime responsible person is the equipment owner right so mainly maintenance directly associated a employee safety while doing the specific coming it's methods it is the employer responsibility to choose from the various standards or the methods that they can adapt to right so if you look at some of those areas when bringing in the third-party contractors to do any type of the maintenance task still you do have this employer or the owner of the facility or the owners designated representatives responsibility within that equation so make sure that it's not just the employee you has to be careful while performing the tasks it's more so the employer or the owner has to provide those tools and resources for the persons before the perform task okay so if you look at the maintenance line which from enough PA 7te 2008 in addition there's one definition that's been added it's called maintenance condition ah this is the state of electrical equipment considering the manufacturer's instructions manufacturers recommendations and applicable industry codes and standards and recommended practices so if one just dissect into the specific language what it's saying is you need to follow the manufacturer guidelines or instructions when you're performing this maintenance tasks right you need to go back to the instruction manuals and installation guidelines provided by this manufacturers on their scheduled maintenance activities or that specific equipment right and if you don't have those then you can go on follow the consensus standard it's like an FPS 70 B or and similar standards right and also industry guidelines per se and then if you look at the next bullet which is article 1 10.1 conditions of maintenance has been cut out even that specific section within article one 10.1 and then when you look at the one thirty point five which is estimate likelihood and severity of this risk analysis of this electrical hazards you need to also take into consideration the condition of the maintenance of the equipment itself not only the work of qualifications and installation guidelines you need to take into consideration what those requirements or the maintenance condition of that specific piece of equipment killed okay so I'm going to talk in few slides about the Occupational Safety and Health Administration score of federal regulations what I'm showing here is 1920 or P LTE equipment must be free from the cognized hazards that are likely to cause death or serious physical harm 10 points in simplistic terms needed to make sure the record point is well maintained it's not posing any kind of imminent danger or hazard the people who are working on that equipment that's how OSHA connects the dots when it comes to the maintenance of this equipment and then if you look at the 19th and 3:34 if there is the evidence of damage that might expose an employer to injury that defect or damaging items including hoop so if an employee of the worker is performing a task or if he is doing an inspection around that equipment right and if he comes across a red hearts part or the temperature rise or a small arcing inside this this person has to make sure that he informs the employer and they take the corrective action so that the tip this defective equipment out of service and then the performance tends to take care of that so then 303 internal parts of ultra at the plant including the bus bars wiring terminals insulators and other surfaces may not be damaged or contaminated so this is directly connecting to any type of loose connections within the bus bars or the circuit breakers or the bus - which over electrical current carrying conductor we need to make sure that these parts are maintained such that there is no contamination or damage to any of those the next one is the 1933 or P no damage or that may be adversely affect the safe operation mechanical strength of the right so you can't how equipment running if there is structural damage or the mechanical strength or integrity of the equipment itself okay so this is a table 135 C technology one of BA 70e which considers equipment condition to be normal if all of the circumstances apart so if you look at the step one through six this is primarily talking about the equipment is properly installed in accordance to the manufacturer recommendations which goes to NFPA 70 right NEC code they commit is properly maintained in accordance with the manufacturer guidelines in optical industry codes which is again what I talked about on the conditions of maintenance all right and then the third bullet is the equipment used in accordance so you need to make sure the equipment is not used then what it is designed a good example would be you can't use an overhead system or high voltage or you can't use a low voltage cat for so it cat three duty test instrument on a cat for applications this is one that I'm mentioning gas use in accordance of the manufacturer guidelines so there's this direct connection between how the equipment is installed and also how it's used if you take the application context and also if you put what the manufacturer has designed this equipment to you okay so you get my doors are closed and secure so you can't say this system i a normal operation keeping all the doors okay I mean if you wanna talk about an example of a thermography it is allowed because it's a diagnostic work and somebody is doing this measurements putting a temperature monitoring in opening the door and this people are qualified persons as well for NFPA 70e and equipment covers are in place and secure and there is no evidence of impending failure such as arcing lower heating looser bound equipment parts visible damage or deterioration so this is basically when you go and look around this equipment physically just a walk-in inspection you need to make sure that there is no visible or imminent failures that's their brands equipment so this is again from article 132 4 which is a normal operation the same thing basically you need to follow the six steps before you think on before the equipment is considered as put in a normal operation ok so chapter 2 talks about the safety related maintenance requirements when it comes to electrical equipment so this is part of NFPA 70e which talks about the general maintenance requirements the requirements for the motor current protective devices or CPD's identification of the components identification of circuits and conductors I'm going to make a quick disclaimer because this topic is so vast I kind of pick and choose what does important factors when it comes to on a day-in day-out basis but it looks at the maintenance and how to maintain this so I skipped few areas like the the batteries I skip the areas on the hazardous areas and also a few other elements within that as well okay so article 205 talks about the single antagonist the first thing is you need to make sure the electrical system single lines are kept intact and they are maintained so that the person who is performing the task is capable of reading those and interpreting those assemblies because if SLT is not updated if you make any kind of modifications to the trip settings or to the location of the breakers that could change the entire thing right so then though this person is qualified he is not aware of those imminent dangers on the list that's exposed to you or they could be a change in the trip settings that could put a different flash category on the same piece of equipment which without knowing this changes a user or a worker who is working around that equipment cannot foresee those criteria okay so article 2 or 503 talks about general maintenance requirements so it clearly calls it shall be maintained in accordance with manufacturer's instructions or industry standards as I previously mentioned if you want to tie in that OSHA CFAST to this it has to be maintained for manufacture instructions or industry standards so industry standards you can use it only if there is no direct connection to that equipment from the manufacturer provided guide okay and also it also reduce the risk associated the failure and the last bullet equip and what are the waters designated representative shall be responsible for maintenance and document is documentation but it says shall it is like a mandatory language it is like a legal language you must have to adhere so article two a 5.4 volt current protective devices OCPD shall be maintained in accordance with the manufacturer instructions or industry standards and maintenance inspection that shall be documented as well not only you perform this things on a regular basis for the maintenance guidelines is required but also you need to make sure that these things are documented and this reports are kept in place as well because if you don't have the documents and players then it means they did not happen okay so just make sure the importance of documentation is very critical that while doing all these things you need to make sure that you need to maintain the documentation as it relates back okay so additional points you need to make sure the break is maintained properly exercising the breakers on a regular basis for the manufacture guidelines again right and the use of remote mechanisms because the law of this remote mechanisms it's available for break and I can back out so you don't need to have your personal go on physically interact with that within that restricted approach of limited affluent boundaries you can just have them do this and a for remote areas that will minimize that exposure to that has it and repairs and modifications are performed using authorized volume guidelines so this one is really important because whenever you make any kind of service work for your MCC be or URL break you need to make sure that these things follow the manufacturers guidelines and if you make any kind of modifications to the gear a good example be you just put I on Windows for instance right so you need to make sure that I have Windows aligned with the manufacturer guidelines and the volume is prude of those things right and acceptance testing because if you make any kind of physical change to the system you need to probably have an HD inspection after the molecules are made to make sure that system is restored to its normal original working order okay so article 2 45 parts about the portable I click tools and equipment so you need to make sure these five things are important because portable active tools on other things which industries use on a regular basis of more frequently right so there are no breaks you need to make sure to check for the core employ equipment that no missing cover place terminations are no straight strands or loose terminals there is no missing or loose altered damaged blades and also make sure the polarity is correct right so make sure whenever you use this coordinate disconnects are portable tools you just check this cords insulation on the strands and everything they are intact before you use that so article 250 is a huge list because this is one of the major foundations of the electrical safety because PPE and the protective equipment and personal safety comes very very critical I'm highlighting this 14 things here at Gandhi took my and Hart States because this role used if you take the electrical safety in the context these are the things that the electrical qualified workers will use on a day-in day-out basis so the bring of predominant focus on this specific area because there is a huge need for people to make sure the things that will protect an employee in case of a hazard or properly maintained and also tested on a regular basis to make sure that there is no deficiencies not bad so inspection testing so if you take this 14 items what is showed here so you need to have the visual inspection inspect for damage of the fact before initial use whenever you put this first on service you need to make sure there is no damage so visually inspect that and insurers thereafter you need to make sure the service conditions are maintained so the max this a is basically one year no case you'll exceed one year unless specified by court or a local authority or a federal and state one so you can out of those unless otherwise there is the change defined by this regulatory body okay so test installation of the product equipment in predictive tools used as a primary production from shark has to be tested no case that shall exceed the years once in three years you have to make sure that your things are tested and the optical 250r are three talks about the safety governing equipment so you need to make sure do the visual and also testing the visual includes the cutting protective shielding damage to conductors in it make sure the crafts and the strain relief of those devices tightness and the inspection shall be made thereafter as condition required so basically if you perform a task right and then you perform a task after like two days or two months I mean there is no nothing wrong in going and tree inspecting or looking at it for a visual checks to make sure there's nothing else broken all right say the time you put it back and service it's always good just have it with your check to make sure there is no signs of damage and testing has to be done prior to the return to the service equipment that is modified our repair so whenever as I mentioned before whenever you perform any kind of a maintenance or a first line you need to make sure that that equipment is tested and according to the manufacturer guidelines or the industry standards before you put it back in the service condition so grounding in testing devices on the rear here which will be stored in the clean and dry area and also shall be inspected and tested before every each and every use so this is the one thing it's not like once in a year or once in three years you have to test this and inspect this before each and every use and if one look at what those guidelines are is defined a right click is the 37:26 which is the standard for 4.76 kv 2 38 kv gown and test devices used in enclosures so the next one is article two 50.4 test instrument is one of the priority areas where our greatest players significantly using the portable test instruments for absence of voltage a presence of voltage testing this applies to portable test instruments in this area specifically the column bar if you're using this device for verifying a presence or absence of the voltage it has to be maintained I showed the functional entirety so I mean most of you know that article 120 point 5 requires the live deadline passed right so you need to make sure the maintenance program includes the functional verification you need to make sure that portable test instrument is calibrated and verify for the accuracy and also assure the functional integrity is maintained when those tests are being performed so make sure that your test instruments are maintained and calibrated to the back the next one is the fundamentals of electrical equipment maintenance so you need to look at the design for maintainability so whenever you look at this is again taken from NFPA 70 B which talks about why do you require the electrical equipment maintenance program right so before even the maintenance comes into play there's a design aspect right so when the company's particular design specifications they need to look for the design for maintainability criteria that's clearly defined right so a simple example is you don't want the deck of mine to take about 15 hours to change a small fuse if it requires this for like 10 minutes right so just make sure the things that requires the maintainability or kept in a place where it's easy to access whenever there is a maintenance task must perform so what I'm trying to say is doing the designing functions of any type of electrical equipment you need to consider the design for maintainability feature that will give the safe and easy access for the qualified persons to perform those tasks for the manufacturing guidelines I think end-users can also ask for it in some cases and most of the manufacturing required design specifications provide that as well so coordinate the maintenance activities with parent connection outages we that there should be interaction what I called between the manufacturing groups and also the production groups make sure those two departments are working in sync the reason is you don't want to schedule a me and Zack tivity on this when the people are running this thing at a 90 percent production and the production or the management is replying the high hog right so you need to make sure that the maintenance operations or these things are performed in sync with the production outages so you can align this activity so there should be a dialogue between the production and the maintenance teams so something equipment concerning future growth so these are second all the things that I refer to as design criteria before you you're designing an equipment for this facility right so you foresee you next five years or six years what is this projected load is going to change and you can design the equipment so you don't need to go and change the equipment that given three years or two years time so always make sure that you have a future growth capability is built into your equipment for example you require three thousand hours for example complete Fallone right so you probably plan for a five thousand or a four thousand five hundred depends on you foresee that there's going to be an increase to that load so that you don't change that main breakers on a short-term basis and cost of maintenance leaplet replacement space necessary for this fundamental maintenance practices has to be also taken into consideration because you need to understand the impact of various types of equipments and you want to standardize those to make sure that you have the same type of breaker and you have two additional in your spare so if there is something that goes wrong you have some you have this extra spare that you can dis rack in and become in the production to normal right and also you need to make sure that you are deep Lessman spirits like your fuses or any other regular consumables are kept in place as well so benefits electrical preventive maintenance effective scheduling activities and what I call that icky scheduling here is basically you perform this maintenance functions or plan this maintenance activities around your production outages and also you have that scheduling that's been done based on the prioritization of the equipment so limiting out its impact on operation because if you know what is the maintenance condition of the equipment you can basically predict when this equipment is going to fail or what is the next thing that we need to do so in that way you can limit it limit the outage impact on operation so you can give more time to your manufacturing operations and next thing is coordinating the spare parts so if you have a planned schedule in place you can basically forecast what is the consumables or the replacement spares its required for the specific activity and you can bring them ahead of time instead of just hiring the Machine shut down on a chaotic basis when you need to expedite the parts that expedite the labor and also spend too much money on overtime costs and people going through taking some shortcuts as well right so make sure you have a proper tools availability when performing this task make sure that they are the right tools and the protective equipment for them to safely perform the status and last but not least make sure the person who is doing this task is a qualified book because qualified workers are not available or illegal it builds its time they're not freely available in the industrial setting right so you need to make sure that the qualified persons or available to perform the task so that you're not having somebody else who is not qualified perform the same task that would create additional has okay so here are quick comparison between maintenance versus risk exposure so when I talked about the maintenance aspects we talked about the corrective which is more like a right to failure and this is next as a preventive and the third is a condition based okay aren't afraid you you don't do anything you go and attend to this task but something breaks down right so something breaks down you're going to have you Paula five persons a whole is available on your share you just gone up into the task and fix that so I call it higher because well people are under pressure to the fungus task right they are taking short curds are not done in the PPE and that trying their main motive is to just get it done fixin coming back because the how among us pressure when in fact the next time it is a prevent you were scheduled based it is limited risk right now you just doing this maintenance based on your clock rights based on availability of cables now right your maintenance outage time which is flying right see you exposure to hazard is limited the risk is limited in this case because in high res spaces or high risk actions and a collective approach you are taking shortcuts are not only the PPE are you trying to on a firefighting mode get things done whereas the prevent to you you know what those things has to be coordinated and organized so your little skills limited in this way all right I'm gonna go to the condition bills which is more like extremely low risk because in this case you're not just planning these acti ities or performing this based on the scheduled maintenance guidelines or activities as what it's defined you are more so monitoring these conditions of the equipment what about practices using some kind of a sensors or some kind of power monitoring systems are remote monitoring or capability tools that gives you a trend over time where you're monitoring the condition of the equipment and then applying the people when there is a need so that brings your is extremely down I thought this is very important because as you look at it the more you go on like the failure approach you're exposing your workers to your higher risk compared to the condition based one you are extremely lawrence right so time to be of sorry chapter four of 70 B talks about the racial failure is inevitable and if you have an EPM in place by its electrical preventive maintenance program in place you can delay those failures so more so like it's a applied one so you can delay this and you can ensure that people are working on this and the equipment of time is given to your production capabilities and ROI is pretty big because when you try to do this maintenance tasks in terms of prevent you to correct it right spective is about five times what industry says is about five times what it would otherwise cost for preventative maintenance right if for example you are spending a hundred thousand dollars or bringing an equipment down because you know that is the only maintenance has to be completed right and then if you have to do the same thing if the equipment shuts down you are not only taking into consideration the cost associated with that specific space or the time the work is performed in search you are also adding to that multiple ways you adding your supply chain you are a customer value right you can get your goods to your customers on time and I cross or affect the entire supply chain and this puts all this automotive companies and their downtime is by twenty two thousand dollars a minute or so and the same thing with data centers and staff so whether houses hide redundant systems in place to just mitigate those type of risks okay so you have ingredient and system doesn't mean you don't need to do maintenance you need to do maintenance basically to ensure the resilient systems also punish them if there is me so break it maintenance so these are the major things which we come across right so low voltage power circuit breaker should be inspected on an annual basis and also the test has to be similar to it and one for conditions once in every three to five years because the main reason here is not only you just how the breaker that's sitting there it's gonna function when there is a fault occurs right you need to make sure the system is going to perform to its design function like a tripping in terms of the breaker the breaker has to strip in case of fault or in case of outlet condition so how do you know it you know it only if you test it so the testing has to be done in with reference manufacturing guidelines small Salwa industry steinege the next one is the english with a few spare breakers right so as i mentioned before you can have the similar identical piece of equipment in store like two or three right so that will help you basically if something goes wrong you have something in spare you can just bring it in and put it back in selves the in-service breakers could then be exchanged it spares at opportune time I mean these are things where you can cut down significantly because the the more you can down the downtime it's going to help you to keep your operational output and productivity measures on a high rate okay since the Seabees this whole point I came across this one 30.6 requires determine the cause of break a trip so this is one thing which most of us we do you in your residential breakers as well right so the first tendency is basically if something trips we go and reset without knowing why trip in first place so 70e specifically requires article 130 got six requires to determine the cause of the breaker trip before you go and visit so there could be a for the other side that for the break-up trip you need to make sure not going to close on the for okay so are also non qualified persons are not allowed to reset the break so i'm not sure how he will really follow this right it's industrial setting because an operator can go on look at the breaker the breaker tray and then because of the production produce you just got it just a switch I can go on put it on and now that could be a huge risk for this person right must be replaced if a girl trips on document so if you if you're seeing a regular pattern of this break of stripping or a nuisance tripping it could be because of four o'clock now you need to make sure that you take this break it down and verify its functionality is checked before you put it back or replays that if it's doing that on a regular basis so this is a slide we're employing a picture because all these previous slides were pretty text-heavy so I want to show you some pictures here so this is a loose connections where you look at some of the stones got burnt out the one on the right here on the top here is a busted flash over on this one of the Facebook incident the short three years ago and here's one of this odd contacts here the point I'm trying to make here is the loose connections about the major things when it comes to our electrical flash shovels or the odd faults in search right so the degradation over time will lead this kind of scenario switch could be completely preventable so if you look at the threaded connections on Saturday 11 from NFPA 70 B it's important for thread connections to be properly tightened so tightening the connections brings two questions is are you titling this to the proper talk or not are you just for talking and under talking right so in the verifying the taught values of initial inspiration is not reliable so some people say that hey I'm just bringing in the equipment from the manufacture site who's shipped it to me do I need to retort this yes absolutely yes because there's a high possibility because of the storage requirement so because of the transit requirement for the shipping this contact would have gotten losing right you need to make sure that you go and we check the torque values or it is normal for the metal access also to occur after installation point so the regular tour tightening techniques must be used and they need to be used accordance with the instructions for mind and 70 B or an Samhita which I have it in the last slides where you can go and check for these values reference polish sphere is the temperature modeling system so it's kind of showing multiple things here so in one to the left is the thermography using open door tomography or closed or tomography using a window or camera this is explained in a very good depth in Chapter eleven not seventy in enough PA seventy B now you need to make sure that you follow this temperature monitoring because on the previous slides I showed this loose connections these loose connections can be monitored using there's non contact type devices where you can now monitor the temperature are using tomography as one of the tools but but you need also understand the pros and cons of every technology so you'd understand whenever you do the demography program you're not just shooting an IR camera like at the airports what people are doing right now to monitor the temperature so you need to make sure the tomography scanners are certified right they know what they are looking at they know how did you put the values you know what temperature's of what scans they're in it doing and then they need to document this values as well thoroughly so it's not that unless otherwise you have a qualified to model for in your team don't just take a camera and just look at things it doesn't make any sense okay and then what I'm trying to the right here are some of those remote monitoring devices the one that's yellow here I'm just pointing on the screen it's basically the hot spot monitor which is a gray zone product temperature monitoring device and I mean the advantage of this device is basically you connect this using a non-contact fiber-optic technology so you can monitor the temperature measurements remotely so in this case you don't need you and how the toast proximity of the gear right you don't need to expose your persons in terms of the clothes store the same room as well you can have someone sitting in their scattered home and then monitoring the temperature it's a great value because the again go back to the story where you mentioned you go on the condition based monitoring tools your risk is extremely limited okay and then other things and that means fixed IR camera and also there's one more horrified attacks I mean there are several techniques available the marketplace but you can go and evaluate everything comes with pros and cons but the the biggest point I would like to make on the slide is monthly is what are the technology you are using just make sure that your employees are trained in using those and then this thing or a document and to know how to interpret the data as the devices do to you okay that's pretty important so this is the next slide that the matter if inspections temperature range because it's most people ask what is this reference point this is taken out from Alameda standard 2019 so as you look at it anybody does the temperature of 1 degree 10 degree C that shows a possible deficiency warrants investigation meaning you do this inspections right you do this continuous monitoring of the temperature and then the system tells you there is temperature within this Delta so what you do is you just don't lose it right you need to go and make sure that you need to do additional investigation to make sure understand what is going wrong is there any kind of a correlation between other parameters or if the system is doing anything wrong functionality you need to make sure that you go and throw the monitor investigate the equipment to understand the underlying concern or the factor okay so if there is anything on a 21 to 40 degrees C 100 corrective measures can be accomplished right so that the what it is when a discrepancy repairing me so you go and see something that's laid heart or body deeply see you just go and make sure that you perform this so the one more point I would like to add to this is not just the one to ten degrees here it looks pretty normal it's a possible deficiency warrants investigation if you look at all of the same standards that appear 70 be left with steel the insulation degradation over time and how it relates the temperature right so 10 degrees C rise in the operation of the equipment right so though it doesn't require require an immediate investigation of moloch but in retrospect it's going to affect the moral longevity of the equipment for example if the equipment is designed for 30 years like right and then you run this 10 degrees C high so what that's going to lead you to only 15 years so you're operating your capex budget is gonna put again 15 I mean people to dream I mean we buy this equipment whatever then is to change this in 15 years over 30 years this design operational life 20 corrections methods for fi from tightness of 3 shall use the low register so major to compare the collection seminars the guidance taken out from 70 B verify the tightness of accessible connections terminations and calibrate the thought measurement tool so not only you verify the tortes on this connections you also need to make sure that your thought tools or calibrated as well and perform tomography survey or temperature monitoring systems on a regular basis right so I mean tomography programs some people do like once in six months or once a year this makes sure what are you documenting you're documenting the accurate data and then second thing is you're comparing those things on on a periodic basis meaning you do this today and you do this like you're later I just go back and look at your previous measurements and check for the baselines and what is that variation it but if using a temperature monitoring device my condition based technique using any type of remote sensing tools it's going to give you the trend over time automatic so you know along with that there's a lot of technologies available and we do few of those as well where you can take the temperature data and then combine that with any kind of the current measurements of voltage or frequency dips and then make determination how this guide is relevant and what kind of corrective actions has to be taken to the defect okay so this is a slide for torque value use electrical connections it's sample only I'm in now and see meet our standards calls out like six tables on this so make sure that you follow those and down now this is just for reference purpose okay and then the article 225 talks about the fuses the shall be maintained and free of visible breaks and prior cracks fuse clips are shelved but if the typo shall maintain the adequate contact with the fuses and last but not least you can make any modification 70 clearly states that you can't make a modification to the fuse modify to allow the insertion into a current limiting one you can't use a non current limiting one and put it on a current limiting because it's a two different purposes period so article 225 and 225 three talks about insulated case and market circuit breakers now you need to make sure that inspector clean they furthers the visual arts the contamination dust and debris contamination is one of the important things of like to emphasize here because in the industrial setting you see lot of this contaminants on this breakers right so movies shall relate to ventilation requirements and which will in turn result in temperature rises when the temperature rises the contacts go bad or the equipment goes down right so just make sure that you monitor that bridge loose connections excess it can cause a malfunction nuisance tripping and failure as well and our but also whenever you're trying to look at the breakers right so breakers are inter the Falls near the interrupt rating must be tested before you put it back in so I mean the reason they're calling is the breakers are not meant for like five four right whenever you use this breakers they're not rated for I forced to hand out they just tested for two and they're designed to just handle only one so when the things are handling this falls on the max to make sure that these devices are tested back to make sure the functional integrity is maintained okay our system studies all the important things so electrical studies are integral to design operation maintenance as I mentioned before on your you now single line diagrams you need to make sure the short-circuit studies of done on regular basis coordination studies load flow analysis reliability studies and also a risk assessment studies as well so load flow studies show are basically the direction and amount of power flowing from variable sources to the load and then the short-circuit of fault currents represent a significant amount of energy can be electrical systems and make sure that you do the studies on a regular basis there is a guideline here I'm just looking at it I think it's a five years or so on this short circuit studies if I'm recalling it right and the reliability study is conducted based on the facility electrical systems to identify the equipment and associated risks right so as I mentioned before risk assessment studies should also take into consideration the maintenance condition of long with the equipment operational criteria environment and also the qualification of the persons handling us protective ski maintenance ensuring the productions operate you ensure the single lines are up-to-date and lubricated and clean the protective parts and verify proper type and rating of the fuses so you have to make sure that whenever you place the fuses you're gonna replace that with the proper type and rating so the functionality is not compromised okay so test and test methods determine whether any corrective maintenance or replacement necessary on little or deserve so whatever you do testing your just understanding but there's any c rrective action is required right so like a thermography program or you're checking the tightness of the boards and nards you need to make sure that what kind of a corrective action needs to be taken not only just monitoring or testing those to ascertain the ability of the element continue the performed design function adequately so to make sure your systems is designed or it's producing the same test values is what it's supposed to be giving out so basically and Sunita RFPs out DB has definitely of guidelines and the tables to the defect so just go back and look at those and that's available signage to buy as well from an SI website so to chart the gradual determination of equipment over its service life so as I mentioned before just as an example of the demography on iPod testing or installation resistance on a dielectric strength you need to go back and look at this previous records to make sure that this thing's how do they compare and what kind of a trend it's showing you so that you can take the appropriate corrective action okay so life expectancy of cultic like a plant this is like loud from the sources of ie I Triple E Goldberg ABB and Sealy a so if you look at the platformers the design for 25 to 30 years on circuit breakers are 15 to 20 switch modes and to secure 30 to 40 years that is enough time to call here is the expected useful life is one and the actual life is a secondary thing right so that actual life is going to be dependent purely on how you maintain the equipment that's been originally designed for so that again brings back the question of how do you maintain this on a regular basis per manufacture guidelines relevant standards in the industry okay so this is one of the charts I think because most of times people has a question how often are fake when I need to do this is a good guideline I took few snapshots from the and similar standards this is the main test frequently frequency metrics you go and evaluate the equipment based on the criteria the equipment condition you know how your equipment is right so before you start your car you know what's the condition of your car same way your equipment so you can go on self-rated equipment based on poor average record and then all the scores right and then I built requirements if you're looking at a medium or a high reliability you take this points on five on one score and then you go and take this and apply this fight for I'm trying so there is a new installation a system modification when you try to do the power system studies these are the things that needs to do five years this one has taught into five years since last Sunday in certain analysis has to be gone and there is like a lot of changes has been brought into place the toy tripoli 1584 standards in 2018 Cisco makes sure that you are verify that calculations instant energy or flash calculations to your cooking any form a restoration make sure you make those adjustments will require so these are the definitely visual visual and mechanical visual mechanical electrical all three different categories for different types of ultra equipment right so the and similar standards kind of define those in various buckets like a switch gear switch board assemblies or your lower page low energy for example let's look at the infrared infrared visual electrical mechanical right it says twelve months here so Dan you go and check this based on your liability requirements and where you are looking at reliability needs of this and then understand evaluate the condition of the equipment has it set and you apply that factor and that's a frequency should be using when you are performing this type of tests okay this the good reference chart I mean in the end of PA and sorry and C meter standards is a film a three-page document it's a wealth of information can just go and look back and you can use the maintenance programs to be more effective okay so these are all the different charts and tables that you can use that defines what those frequency of those maintenance tasks is to be then you can adjust your programs accordingly okay I think that's about all I have got for you guys and we have 10 more minutes as I'm saying the Train seven minutes I will take any questions please go ahead and use the questions pane here so that I can answer those questions it's not information I mean 70e gives the safety work practices but 70 big used to the complete guidance on what those maintenance requirements are for and that has like detailed information for every foreseeable component as you can see with your electrical systems like from your switch here MCCS breakers transformers bus decks scatter systems yeah I mean it's great information you can this journal in there please laughs slide again okay here is the last slide I'm gonna get on the handout section you guys saw the complete presentation available for you to go and access this just make sure you go and pick this and also as you exit the webinar please please take the survey which will greatly help us in planning your future webinars and also from grills internet products we do have a hotspot monitor which I talked about briefly because this is not a product presentation if you guys are really interested to learn more about it or understand how this product can help you guys solve this temperature anomaly defects atchoo optical and electrical systems please let us know with the exit survey so our inside sales team or the applications team will reach out to you and help you see how it fits your needs you I'm kind of looking at the questions give me one second this is not as easy as a talk especially this questions back or torque and maintenance ship can it look at one after all looking at the table 135 see enough PA 70 is it doesn't surely exactly as if you can use a most every job so the likelihood occurrence will change from job to job correct yes that is correct so you need to look at it based on the equipment basis it's not like on your program level whenever you doing this assessment you need to make sure you use the stables in accordance with that specific piece of equipment and then you evaluate that is equipment condition based and then you assess the risk according yes yes as I mentioned the slides are there for you to download on the same webinar dashboard you can download please note the Dancy torque that please know that ANSI talks back for both titles of our steel that is correct so I did not put all types of boards and different configurations so I just kind of gave you a sample so this is no way complete exhaustive list of everything you need to go and look at I'll say meter 2019 or LF pa7bp to get the torque values across the board so you can get what exactly you're looking for for your equipment what I presented on this slides is just like a slur to give you a feel for what exactly this table to apply you so we had a fire in our mcc whywe fire started on where the cables are playing power to your fan with the 40 HP motor believing fire started at butterflies connected no protection jump breaker thermal ordered fan cabins from 1991 yeah this is the one of the things that's a classic situations very how this temperature anomalies that gets unnoticed and that could lead to kind of a fire right so the consequences are are pretty significant as a result of this does grace PS dais need periodic calibration this again the PSD is not the discussion for this topic here the grace PS days or self calibrated there is no calibration required for the PE SDS or any of the products what we do everything is factory calibrated and there is no calibration necessary so if the device is not functioning you will know that indication from the device itself let me tell you it is time for you to replace it what is Nancy could book again so an zakat book as I'll see meter 2019 that is the standards I can send you guys what is that exactly number as well yeah pool has attended the webinar we get the continuous education credits I think our marketing team will follow up and that will send you the CEU certificate for the 10 dots yes you you however all this p.m. program fit into ia ot since most of them are still time-based that's a very great question because I think the PM programs cannot directly tie into your a IOT as it's it's all you can do is basically take this documentation or the data that's been archived from years and you can take that information to your cloud and the future whatever you are monitoring the IOT based devices using a wireless technologies you can compare the data over the data analysis but these things don't talk to each other you can take the previous information on historians and you can compare the data to what the new devices of monitoring at a current level but you can go back and get it trend all that time or they're not trending from the past because you never had right so I think most of the devices or equipment as they're designed today or coming up with some level of sensors and systems in place or digital switch gear the Collard like Siemens abbs are you terms all the big manufacturers how this digital switch gear you can go on look at the websites are probably the have the ability for you guys to go and integrate the data from your cable system so how does a normal operation of tracked operator or a maintenance staff peepee requirements so I mean the normal operation when think about them and I'm not going to go into this specific thing in detail but I'm going to you a simple analogy right if the doors are closed and if you're performing a task that's more like taking a measurement on a meter that's normal operation if you meet all the conditions of six conditions that's been outlined in FPA 7te right and then if you're opening that opening that cabinet and performing a task in energized condition that's a totally different task that's what I would like to create the difference and the PPE rules apply for your facility guidelines so if you facility requires an arc flash category or out first cuddly 40 Cal PPE to be worn when you are entering article drew you need to follow that because that's not defined by me or the herschel that's your facilities procedures however if your procedure calls for operator you can use the two because what is normal is very subjective term right so from electrical standpoint a word can perform in a charged fashion when the doors are open is not a normal operation that's an assessed work so you need to dawn with the PPE what's appropriate for that much care okay and if it is well that's being performed outside the cabinet and when you meet all the six conditions of that NFPA 70e then it is a normal operation and whatever is construed or defined as normal VP normal operation PPE by your facility unit I hope that answers the question you where did you get the maintenance maintenance frequency metrics came from and similar standards 2019 edition I will send you all what's the reference standards that we use at the PowerPoint so that you have a reference to what I talked in this presentation okay you think we're past the time you need the question skies I mean that please please pick the webinar survey and also my email is there on the last slide which was supposed to be so my email is on the screen plus please please do send me an email if you have any additional questions we'd love to answer those yeah please do take the survey as they exit the poll and exit the webinar okay thank you so much and stay safe guys have a great day and a stay safe [Music]
