Recloser counter?... and other answered questions. 

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.

Hey been watching for a while you hit 100 thousand subscribers pretty quick great job on the content 👍

You're really knowledgeable! Really interesting videos! Love sm seeing these kinda things! Love finding out why my lights might flicker! 😄😁

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!

Pretty hard to make the operating end of a tool out of something nonconductive. Impressive that it happens at all! Thanks for the videos!

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

Congratulations on the 100k!!!!

congrats on 100k

Glad you are answering the question of your comments

Thanks for showing the world how our infrastructure works and how to remain safe.

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.

Extremely informative. 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.

Great explanation, thank you

14:00 Very nice looking transformer!! Still shiny!

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.

Most important thing. No one going to steal your lunch from a pad mount.😂 Stay safe young man.

3:06 Poor squirrel!

You’re the man Aaron, thanks for the video!

One of my favorite parts of the job is mutilating peoples bushes around pad mounts, then i put a new sticker on showing 10’ 😈

GREAT VIDEO

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.

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

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~~

Most Transformers I worked on had a barrier board between primary and secondary

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?

nice to see what they shut off when we are doing hot digs

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.

Thanks

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'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.

Thank you

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 😁)

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.)

3155A@240v is fucking insane amount of energy.

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!

Praying to people in Canada from their wild fires 😊

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

That's obviously a three-phase padmount transformer. Serving that (what appears to be an) apartment building?

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

👍

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?

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.

car guys need those wrenches

Love your videos! What is the process if you were to find a hornet's nest?

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.

👍👊 why DIDN’T you have your truck? Do you have your own mechanics?

👊🏻

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 ?

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.

Which safety glasses do you wear? Are they both arc and impact protective?

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.

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?

I’d just about wrestle a bear instead of disturbing a hornets nest. Those critters just don’t give up lol

Do you have any pole mount transformers in the area you cover that are internally fused by any chance?

Watch that video that is one problem with underground wires

842 thumbs up

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.

we have replaced bad cables to meter

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?

How would low oil temperature at the substation be bad?

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 go over bucket controls and common tools you typically take in with you ? If you havent already.

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.

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?

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?

Can you correct your title

Love the videos don't love the loud lip smacks.

Bummer that fascinating stuff needs to be sensitive and kept secure. Understandable but disappointing.
