A point of clarification on the hydraulic recloser counter. The counter only counts on recloser closings. It does nothing on openings. Love your videos, makes me wish I was still working. Easy to see you enjoy your job.
I'm a retired Civil Engineer who almost became an Electrical Engineer instead. Your videos are wonderful and I would like to thank you for doing them, as well as your Company for allowing you to do them. They help educate the general public on what it takes to keep the power on, and they raise awareness of safety requirements for power systems.
Thank you so much for taking time to share all of that information. It's fascinating to me. My husband just loves when people plant shrubs around their air conditioners and wonder why they don't work and he can't get to them. Please stay safe and God bless.
I have to laugh at the bit with planting bushes around electrical equipment. As many may recall, I have mentioned I serviced generators before retirement and on new installations people usually mentioned "blocking the eye sore" with something decorative. I would reply with a simple rule of some distance while walking around the unit with arms spread.... "we need room to work." I would also mention that if I came to their office and stuck a bush in both open lower desk drawers and their trash pail, then stuck another by the door, would they still be able to do a good job? Ok, let's make them holly bushes (stay green all year) with those prickers on them. All of a sudden that little light in their brain comes on. Recalling a job, late one night during an outage, and I walked around the property looking for a unit with my flashlight. Two laps later I stumble into a grounds keeper who was looking for me. He said the generator was INSIDE that thing over there.... it was a child sized gingerbread house with the exhaust going out a chimney. It was 8 feet tall and fabulous looking, but the carpenter allowed just about zero access for repair, never mind the whole thing was made of wood and a fire hazard. Sometimes I just shake my head!
I do a lot of generator work. We are constantly dealing with people that build fences around them, or have them too close to make up air units. It’s a mess
@@MrSamsamsammy ... joint the club. I did it for near 25 years. At one point, we actually stopped servicing units that were not up to code. (usually inherited from another company) We figured it was starting to be a liability issue. We'd take pics and talk with the customer about changing safety regulations, then explain that we'd be happy to make the necessary changes... for a fee.... or they could let their investment go to pot and have it not function when needed. 90% decided to let us bring things up to code. The rest probably went elsewhere for service. It was a tough transition period, but well worth it in the long run.
just grab the saw and buzz them off, deal with the crying later...
@@throttlebottle5906 ... the difference between a utility and customer owned equipment is the utility owns the right of way, which includes space around the equipment. They don't need permission to clear things, and likely that equipment services more than one home. With a gen set, the customer owns everything. We need permission to both clear the way and send a bill for our time.
You're really knowledgeable! Really interesting videos! Love sm seeing these kinda things! Love finding out why my lights might flicker! 😄😁
Hey been watching for a while you hit 100 thousand subscribers pretty quick great job on the content 👍
Thank you very much! My son encouraged me a ton, I told him 2 years ago that I would never get there.... He assured me I would. Very proud of him and his positivity!
I went to trade school for this but found it too dangerous for me but love to see the videos of someone like you who had the nerve to actually does it
Pretty hard to make the operating end of a tool out of something nonconductive. Impressive that it happens at all!
Thanks for the videos!
congrats on 100k
Thank you!! 👊🤝🍻
Congratulations on the 100k!!!!
Extremely informative. Thank you
Glad you are answering the question of your comments
Thanks for showing the world how our infrastructure works and how to remain safe.
3:06 Poor squirrel!
Great explanation, thank you
You did a great job the last 2 videos you explained the equipment so even people who don't do your work could understand 👍 thanks my friend of course stay safe 👍 thanks mike iron river m
I.
I guess it’s a big advantage when you have linemen who know their territory, customers, and history of their lines and such. I live in a city of almost a million people which owns its own electric system but I would imagine it’s grown too big for the linemen to really know the system like they did 20 years ago and it was a city of 300k people. I know when I lived in the country and we had an electric cooperative, those linemen know the system like they owned it and took great care of us customers. Even though the area was several hundred square miles,there really weren’t that many people. Lots of cows, corn, and cow pastures.
Heh... funny you posted this today. My power flickered this morning. It was just enough to trip my UPSes into standby, and then it cleared. I checked the outage map and one appeared about 6 blocks away near the sub-station that feeds my neighborhood affecting about 50 customers.
GREAT VIDEO
You’re the man Aaron, thanks for the video!
Thanks Mike! Appreciate always seeing ya here! 🤝👊🍻
@@Bobsdecline Appreciate you taking the time to make these videos!
14:00 Very nice looking transformer!! Still shiny!
I'm always scratching safety glasses so i bought a box of those nemesis clear. I liked them ao much I bought a box of shaded to wear as my daily sunglasses.
They're great for scratch resistance for sure!
I've also found a few companies that sell decent "cheap" personal use sunglasses that offer free lifetime replacement. Fellas at work started wearing the "shady rays" ... I thought the ad seemed kinda sketchy, but ordered em on a boxing day sale. Already lost a pair and sent them a message and they sent a brand new replacement pair free of charge! I think I paid $40 Canadian for em
I survey and inspect utility poles for a fiber optic company and you wouldn't believe the number of things people block the poles, pad mounts, and underground boxes with. Actually, you probably would, but most people wouldn't believe it. Twice I've come across poles that people had built sheds around, with the pole literally sticking out of the top because they've enclosed the area around the base. I'm just glad I'm not the person responsible for going and telling them they have to take down their jerry-rigged shed because you can't block the pole like that... Or build a roof that close to the lines.
Most important thing. No one going to steal your lunch from a pad mount.😂
Stay safe young man.
Correction, nobody will steal your lunch more than once from a pad mount.
@@LatitudeSky
One big flash and you got a burnt sandwich and a burnt body still holding the sandwich
Really like your videos especially introducing the transformers. We haven't exported transformers to Canada yet. We find it interesting that usually the windings for the pad mount transformers in America and Canada are aluminum instead of copper. Waiting for your new videos~~
Thank you
Hey man, I just graduated from climbing school, I got my osha 10 , CPR/First aid, and my class A driving permit. What union/contractor do you work for so that I can apply. I’ve always watched your videos and they helped me out so much ! Thank you if you do get back to me
IBEW! Are you in Canada or US?
@@BobsdeclineI’m in the U.S brother ! I’m out in California but I don’t mind moving states
One of my favorite parts of the job is mutilating peoples bushes around pad mounts, then i put a new sticker on showing 10’ 😈
nice to see what they shut off when we are doing hot digs
Aaron, how's your air doing? I'm over (down?) in Maine, and we've been gifted a low pressure front that's just sitting over the state, keeping all the wildfire smoke away
Which makes me wonder, does your company have any special procedures or considerations for things like wildfires or ash clouds?
Air here is 100% ! I was quite surprised... The wind has been in our favour. We had a few structures damaged by fire, had to switch the line out.
Not really much for procedures really specific to foest fire and smoke tho.
When responding to fires or calls in the area, if we can't work safely we'll find an alternate plan.
Typically de energize lines that are in a direct path. Usually coordinated with whomever is in charge with the responding Fire dept
Thanks
Love the videos, I've gained a lot of knowledge just from your explanations and demonstrations. What's the craziest thing you've seen inside of a pad mount when opening it up? (critters, but all stories welcomed 😁)
3155A@240v is fucking insane amount of energy.
That's 3155 amps of primary voltage, much higher than 240V. Not sure what is typical for the system he works on but the utility I work for is mostly 13.8 KV and 23KV. It's an incredible amount of energy released in a primary flash
Most Transformers I worked on had a barrier board between primary and secondary
I believe that’s a requirement in NEC regulated installations. That’s pretty much the only difference I’ve noticed between utility transformers and the ones I work in. We have a few customer owned substations I’ve been in and some have had barriers between the HV and LV side, some haven’t
We have substations in Estonia that separate HV and LV with a wall or have separate rooms._
That’s probably because it’s a live front
@@kevinkovalesky380 I’ve only seen live fronts in extremely old installations. I never paid much attention to the barriers, I’ll have to keep an eye on it next time I’m out at one
@@DjResR Pretty sure that is normal in most of Europe. In Norway the transformer itself is not part of the housing and can be removed. One side of the box is HV and other is LV with separate doors for access.
Question @ 5:18 "That is probably close to teh sub station being such a high current fault"
Is that because of line impedance ?? Lines running parallel induce current. Seems like a long run of a magnetic field would dampen current flow.
Do transformers / cap banks make a difference ??
Yes, it is not voltage but current. We did a tool check on a 480V 3 phase motor controller but still left a wrench on the buss bar. From outside the room I felt that deep concussive blast. Not rock concert strong, it was black power cannon strong. Hot metal was sprayed outward from the contact.
I was just watching some of your older videos where you were talking about using a impact for low voltage works and the hazards associated and I was curious as to why not use the 1kV rated isolators made for impacts? I use them with batteries (50V - 1000V primarily Li-Ion) and really am only familiar with DC HV apart from working with 480V AC lines around the facility and the impact isolators have worked great for me. Would love to get your perspective, also keep up the videos great for always learning something new about electricity!
Going into detail on padmount clearance was quite interesting! We have a couple dozen of them in our neighborhood, and to my knowledge there's actually generally very good clearance on all sides with *most* of them. Some of them are right next to dumpster enclosures, with the side that opens facing *away* from the fence. Less than ideal, but could be worse... minus the part where said side that opens is typically a foot away from the nearby sidewalk at most. Get the feeling that's not entirely *safe.*
Things being half-assed is nothing new in this neighborhood though; it's pretty readily obvious that it was built relatively cheaply, with real questionable decisions being made with some aspects of construction, and from what I can tell the original way it was fed with power was *real* janky. There's now a complete line going past the front entrance and up the hill, but once upon a time there was just a half-dozen poles starting from in front and going a bit up the road to a bridge, where it went into insulated HV cable *across the road* to a pole on the side road said bridge goes over, where it went back to the usual arrangement atop the poles.
I have no idea why it was done this way instead of just running power from the intersection not even a quarter mile down the road, but I assume the reason it's *insulated* high-voltage while making the jump from the main road to the side road is because topography made it hard or impossible to properly get a high enough pole in-between to maintain adequate clearance from the ground below, due to the side road being notably lower in elevation than the main road. This particular run is actually still in place, which is how I even know about it, but the end on the side road now has an open switch on it, so it's likely only there if needed as an alternate feed.
(I've been paying a lot more attention to the power lines in my area ever since I started watching you a few weeks ago.)
Thanks for another educational video Aaron. Do you guys use cable limiters on your parallel feeders low voltage side of your transformers? Or are they just used in UG vaults?
I've seen some pad mounts hat have double doors and an internal barrier between the high and low voltage sides. I think it was a ABB unit.
LOL I love how you said low voltage, of 600 volts.... I would say 12 volts would be low, but I know you work with hundreds of thousands of bolts on those high lines! 😂 Stay safe out there man! Bomb suit electrician away.
That's obviously a three-phase padmount transformer. Serving that (what appears to be an) apartment building?
we in germany aleways use face shields and special clothing during work on switchgear transformers even in houses at the main fuse box
Check you from suriname
going to see my friends and my aunt in the 7363 C822 area very soon , my old place i used to live , a question when the electronic reclosers activate for a event ,do dispatch or E.C. have a notification automatically or only after the line is out partially or completely ?
Love your videos! What is the process if you were to find a hornet's nest?
Which safety glasses do you wear? Are they both arc and impact protective?
Do you see or use partial discharge detectors for the utility you work? They seem to be getting more popular for underground MV cable insulation degradation monitoring.
car guys need those wrenches
they'd break them in half, many are brawn over brains and think 900000 ft.lbs. torque is needed or when breaking rusted things loose. le-snap. leave those for electrical/utility servicing where they need electrical isolation.
Do you experience more ware on tapchangers due to users with solar-PV?
👍
So does the substation building itself have its own meter? Or it's electrical needs is just tapped from the source and not metered?
Oh man, no face shields outdoors? You lucky buggers. We had to use face shields to pull 240V customer service cutouts UNDER ALL CIRCUMSTANCES (not that anyone really did...) the only time we actually tended to use them outside of audits was pulling anything porcelain-encased. Hand grenades, I called them, if they flashed over.
i can tell atleast that pad mount is a 3 phase unit by the colors on X1-X3 atleast for 208 3 phase...its amazing what you can learn from videos and im not even in the electrical field
Never trust colors to show voltage. Always test it with a meter
@@MrSamsamsammy usually a padmount like that would be a 208 panel a higher voltage one im sure would be bigger than that one
@@dawn1berlitz this one could just as easily be 277/480 or more likely since he’s in Canada 347/600. Size is determined by KVA
@@MrSamsamsammy You could see the ratings label on this one. 208Y/120V, 300kVA.
@@eDoc2020 typical larger residential/light commercial power.
Praying to people in Canada from their wild fires 😊
👍👊 why DIDN’T you have

We have a contract with a large garage. Truck was throwing codes for emissions/exhaust problems 😔
@@Bobsdecline it’s never good.
👊🏻
I was wondering what's wrong with the US grid in general. I mean, I got some friends in the US who tells me they have outages of a week multiple times a year. And outages of a couple of hours like a dozed times a year.
I live in Germany, the last outage I noticed was like 20 years ago and planned, with a week notification - as the transformer was changed out for the street. Lasted 3-4 hours or so.
I don't even remember that the lights flickered once in the last 20 years.
Much of the US is more rural with overhead wires and much more extreme weather (of all different kinds) than in Germany. Here in Chicago pretty much all the power grid is buried and haven't had a second of issues over about 20 years, except for around a 3-hour period where my block was out due to some incident or other that cut it off from the grid.
In my neighborhood there is a tree somewhere close to my house that I can hear arcing in a storm/high wind, I've reported it to my power company 2 years ago but they haven't done anything about it. It's common for the lights to flicker 1-8 times in a storm.
That's careless. In my area, the utility is extremely proactive on that. They send out line inspectors every few months and helicopter everything twice a year, with IR, UV arc and corona detectors. That ship sees everything, and they can do real time compares to previous flyovers to see any changes. Tree crews follow.
@@LatitudeSky What's worse is that I suspect its the house directly across the street from me, I've relayed my concerns the the power company and talked to the neighbor over 2 years ago about it but I guess ill get to see their fence burn down eventually. Since then the tree has grown and is visibly within 2 feet of the line. Also this is Texas where they let us freeze so kind of expected.
Do you have any pole mount transformers in the area you cover that are internally fused by any chance?
There's still a few kickin' around!
Watch that video that is one problem with underground wires
I’d just about wrestle a bear instead of disturbing a hornets nest. Those critters just don’t give up lol
we have replaced bad cables to meter
842 thumbs up
So, if 30 or so owners of Electric cars plugged in their chargers, on at the same time, the same line and phase, could they overload and trip the recloser? Would a sudden, heavy amperage local load simulate a fault condition?
That depends on the normal line load. Full draw on that many cars might be 1200 amps at 240 volts, but is only a bit over 40 amps at 7200 volts. You also have to consider that it's VERY unlikely they will all be at full draw exactly at the same time. In the same breath, not everyone will be set up with a 240 volt charger, which will reduce a 10 Kw draw to around 1.5 Kw. at 120 volts.... which is chump change on a 7200 feeder line. (under 1/4 amp)
How would low oil temperature at the substation be bad?
Low temp is fine, alarms are for low level
someone wasn't paying attention. it's OK, too err is human. 😉
Would you be willing or able to make a video about MSAD and differential potential around equipment that has made contact with live HV lines? All the ones i have tried to use for safety training here on YT are SUUUPER dry and hard to get people to pay attention to. I do all the safety training for heavy equipment (excavators, large forklifts, genie lifts, and big front end loaders) where I work. I also train them on the dangers of arc flash/blast and whatnot. I think coming from a "Good 'ol Boy" would stick better.
This is will.... I've been contemplating it for a while now. I've got a few ideas and only reason I haven't made one yet is because I want to make sure, as you said, it wasn't dry and had some good visual examples. Basically... It's going to be very time consuming to make. I've got a few work commitments I'm behind on and some personal events in coming weeks, but will hopefully get on this soon!
@Bobsdecline - Lineman blogger hey man, I am just stoked you actually responded. And, I am 100% sure that if you make it into a video, it will be excellent, like this one. Like all of them. Stay safe out there! Oh, and one more thing, I have had people argue with me and say that an arc blast at 240VAC is impossible. That the voltage is too low. Or that a normal 3 phase Square D breaker can't explode when resetting. Guess it's a good thing that people in the know, know better.
Oh man, even a 120v line can make a heck of a big arc flash!
When it's tied directly to the grid, the Amps just keep flowing!
@Bobsdecline - Lineman blogger that's what I keep telling them! But hey, what do I know, right? And, you mentioned FR clothes, I do indeed wear FR uniforms at work, long sleeve, long pants, FR high vis vest, FR prescription safety glasses, and a properly rated hard hat. That is what NFPA70E says is required to work on a breaker panel with the cover off, so that's what I do. I bought my own insulated gloves and covers. To make sure they fit and are good. It's not worth the risk. My boss told me one time that he'd been in a particular confined space at work 1,000 times. I told him that all it takes is once and you don't go home. That'll be a risk I will not take.
@@robertschemonia5617 there are lots of 480V installations where the available fault current is extremely high. Voltage does have a factor to play, but the clearing time of the overcurrent device has the most to do with available fault current. Specifically when working in switchgear, clearing times become a matter of seconds and not cycles.
Plenty of big 208 stuff will produce a big arc, but unless you’re working on the line side of the service disconnect it’s unlikely you’d get a full on blast before an overcurrent device kicks in.
I’ve worked in some switchgear that had an arc flash value of well over 100 calories, and an approach distance of nearly 100 feet. It was at 480V
Hey Bob, so I have a question maybe you might know the answer to every weekend usually not on the same day it could be a Sunday or could be the following Monday of that weekend but between the hours of 6 AM and 7 AM I have one blink, meaning power shuts off and it kicks back on and it only happens one time every week around the same time between 6 and 7 AM. I called my local utility they sent a guy out. He looked at everything he went and tightened up some lines on the primary do you know going to the transformer? He said there was no problems there he looked at the doors on the fuse, no problems there, he didn’t check the meter on my apartment. He said there’s no problems there so he’s thinking it might be a recloser but he can’t understand why it’s every week between that particular time so he jokingly said well maybe there’s a tree branch out there it’s just touching the powerline between that time every weekend. Just screwed everybody anyway what’s your thoughts?
Some large industrial plant in the area?
Can you go over bucket controls and common tools you typically take in with you ? If you havent already.
If you poop in an elevator but nobody is there to see it, did it really happen?
Hi! is this a well paid job? Can i ask your salary?
I work in Telecom in Canada as well and people cover up our peds all the time and it's super annoying.
But it's the same thing for us.. if we need into that ped all your stuffs coming out.. sorry not sorry.
now lets see a 346KV cutout opened under load! XD (no don't do it, you don't want to get fired or fried). But damn that is cool to see how electricity will still arc and flow even though it is disconnected.
Can you correct your title
Love the videos don't love the loud lip smacks.
I know eh. It actually drives me nuts
Bummer that fascinating stuff needs to be sensitive and kept secure. Understandable but disappointing.
