- Hey Everyone!
There's a whole lot of information that I just barely touch on in this video...I'm really hoping it's not too confusing for those whom aren't in the trade. I will be filming an in depth video on how to do a termination very soon but in the mean time, I encourage you all to ask any questions that are on your mind in the comment section! I try my best to keep up with answers and fortunately there's absolutely amazing community of viewers that have been very helpful with answering a lot of y'all questions as well!
Be safe out there everyone! 👊🍻

Hello
hey if you can, do you have a name for that tool or a link to one? (the spiral depth gauge for the insulation). id like to mention it to my company to see if we might be able to get them. that would be a very useful tool just to save a little extra time and make it a little less of a hassle. thanks!
In my cable tv days we had an cable stripper like that for the bigger coax cables. did the outside and the inside stripping
"...I'm really hoping it's not too confusing for those whom aren't in the trade." Yes, it is a bit whelming. Before _I_ change a padmount 😱I need more training!! 🤯But I see the general path of the repair and the parts and most of the "Why?". Thanks for showing the insides of those 7KV elbow connectors (bonus: two types!).
Just wondering if you guys have a backyard machine that you guys can use instead of driving a 5-ton truck through somebody's back yard. Had the same thing happened here last year but it was a pole mount they used a backyard machine to remove it from the pole
Aaron, retired electrical mechanic from Fredericton, that strange elbow termination you had there was a Kerney elbow with a butt connection on the stinger. One of the first elbows kits ever made and a poor design. I have changed many of these in my time and these elbows should not be opened hot because the stinger could stay inside the bushing insert and break were the two flat surfaces meet at the end of the lug . The clue to look for is the solid half ring where your hot stick hooks. These elbows were banned in the late seventies early eighties. No doubt there are still a few on the system. If you have that old elbow , compare to the newer ones. Talk about it at your next safety meeting .
Nice! Nobody had any idea what it was at all. Thank you very much for taking the time to explain/share that.
Any one of us would have definitely pulled that hot without a second thought.
I'll certainly let the guys know. 🤝
Thanks for saying that keeping These guys safe !
Thank you and a big thanks to your company/coworkers for letting you film a job like this! I work in telecom but I love seeing all infrastructure that makes our life today possible
More pole eclipses ... from Riverview ... surprises - the stinger boot blowing off, the pressure so high that it bent the lock clasp of the enclosure, a stinger so old that the current linemen had never seen that version! This channel is best when things go wrong and not in an expected manner...
I agree! We all learn every day... Already a viewer has taken the time to explain exactly what brand of termination that was and added a few safety precautions to identify and deal with them. Very cool. Love it when people share knowledge and help each other out.
Wow! Would never have thought the padlock hasp would be that distorted and damaged by an internal arc/explosion ...
My first guess would have been that it got bent from other means however I was just in that unit a month ago and it was fine... So I'm assuming there must have been a blast of some sort! Pretty wild for sure.
@@Bobsdecline any chance that xfmr might have been hit with a snowplow? Just thinking that a blast big enough to bend that tab probably would have disturbed several blocks and someone would have reported the noise first. It also would have deformed the lid.
our padmount slings have a rope on them to hold the lid up for you so you dont have to fight it. very useful, might be useful for you yo look into to save your back! good work brother!
That's not a bad idea! Seems I remember MADI designed a product for this as well, but I've never tried it
Love the channel. Thanks for all you do. Stay safe out there.
Why do those things seem to happen on the weekends? At least the weather wasn't bad. Good thing the structure of that box held. Many years ago there was one where I worked that had a failure and blew the door across the parking lot. It sounded like a bomb. Thank you for a very interesting video. Please stay safe, and God bless.
It's true eh! Always on the weekend lol! That's not a bad thing tho... An unplanned job like this can really mess up the day plan.
@@Bobsdecline I blame lightning, sometime in the past.
It very well could have been!
Could be a loading issue. More people home on the weekends. Drawing more power, overloading a weakened transformer.
Absolutely fascinating to watch all of those detailed steps required to change out a pad mount transformer👍
Great video I keep learning about things I'll never use🤣🤣👊
Lol 👊🤝
I work down in Mississippi for an electrical contractor out of local 917. When we do stress cones at the chemical plant I work at we have to strip em all by hand. Freaking sucks. Can’t get boss to incest in this fancy tools lol
Lots on incest in Mississippi huh 😝😝
Another great video IMO! The energy that that must have blown apart with must have been a lot 2 do all that damage from the look of it! Great job, I ALWAYS find your videos so interesting! I'm not anything even remotely like a lineman, in fact I'm on full disability, but I truly appreciate what you all have to do & the conditions you do it in sometimes! You all make modern life possible & I 4 1 can't say Thank you enough!
Great video, we use the 4 and 6 slot Allen lugs for our secondaries. I like those a lot better than the paddle style with the bolts. You should do a video of doing a terminator install!
I'm supposed to meet with a guy to film one for our company this week! I should be able to make some adjustments to release it on my channel as well 🤞
again very good work and thanks for the update 🤛
Job well done 👏
Really interesting to see this in progress. Thanks Aaron, stay safe.
Thanks for the video. I appreciate the full story.
The (bleeder ground) that bonds the bushings to the frame out in our area the utility company calls it the (drain) ground wire is just for eliminating static discharge if you pull the elbow hot?
Out here in Long Island ny we make up our own pad mount transformers because the utility will not make them up when they are on consumer owned property.
I love all of your videos. Just a country hick electrical contractor out in the sicks!
amazing!
Crazy! I've seen the can transformers blown right off power poles and those pad boxes blow up like balloons!!
Great video and job changing out the pad mount transformer.
Intriguing. Great entertainment. 👍
love ur videos man! ur the only lineman who really does put a lot of work in showing lineman pov, keep your videos going! i have been watching you along these years and no one has ever been close to match your amazing content, although there is not a lot of people who like electricity (not so many viewers) you make amazing videos for everyone who does like it, hope you’re doing well and thank you for everything, cheers my man 👍🏻
Interesting seeing that you guys use a combination of underground and aerial, it looks like all the customer drops are aerial.
The extra work servicing undergrounds utilities should be instructive for those folks who feel putting utilities underground solves all problems. Here in NH our utilities are mainly aerial but a lot of new developments are underground for aesthetic reasons. When we built our house a zillion years ago opted for a combination of aerial and underground, the last 200 feet (61M). Same construction as you mentioned cables were direct burial. That is no longer allow and underground now must be in conduit.
I would assume that the extra work caused by underground utilities is far outweighed by the fact that they barely cause problems.
And if they cause problems it's (I assume) generally not during a storm. So a lot safer for the lineman compared to aerial lines that regularly have to be repaired during storms and other extreme weather events.
@@Jehty_ That is true. However here in the rust belt they are not immune to frost heaves and errant backhoe's. So you need to balance maintenance cost vs cost of construction. Here in NH since the state PUC "encouraged" utilities to be more aggressive tree trimming we have far fewer power outages.
I am a master electrician / field service tech servicing and testing medium and high voltage equipment. My brother in-law bought a new house, I asked him about putting in a generator plug like I did at his last house. He said no I will be fine all my electric is underground. I said that doesn’t matter, it’s not underground everywhere, he said I will be fine. He had lost power 3 or 4 times in the last year. He texted me and said he wants a generator plug now. I wanted to say I told you so but I didn’t.
@@Jehty_You would be assuming wrong. Underground utilities are just as problem prone as their aerial counterparts. Troubleshooting and repairing is far more difficult and expensive. And even though the utilities own easements where the underground runs, people still build things on top of them. I live in the PNW and our utilities are very aggressive when it comes to tree trimming. A couple years ago we had a massive windstorm come through and knocked out power to pretty much the entire region. Our power is largely aerial. Within 24 hours about 95% of the power was restored and those that weren't were largely due to access issues such as trees blocking roads. I work for a road dept and we were actually out in the storm cutting trees that blocked roads as they fell so the power crews could have access when they needed. Aerial is far superior in my opinion, it just looks ugly.
@@mikel9567well, I find that hard to believe.
I'm German, so I will compare things to Germany, because that's what I know.
Edit: Sorry, I somehow forgot that he was from Canada, not USA. My bad.
I couldn't find a number for the average outage time per year for Canada. Has someone that number?
So in Germany more than 80% of our power grid is underground. The number I found for the US is 20%.
On average a customer in Germany experienced 12.2 *minutes* of interruption in 2022. The average US customer 5.5 *hours*.
The highest average number in the last decade was 8 hours in the US (in 2020), in Germany it was 15 minutes (in 2017).
That's just such an enormous difference.
Of course I'm not saying that that difference is solely because of underground vs aerial.
But a lot of reasons for power outages features on this channel are just things I've never heard of here in Germany. Animal walked on transformer, car crashed in power pole. Even power outages because of trees are really rare.
All power outages (all 5 or so of them) I experienced during my 30 years on this earth were during "storms of the century". I've never experienced a power outage that just happened on a normal day.
👊🏽 watching from Trinidad. Thank you for your informative content sir.
GREAT VIDEO !!!
Thanks for the good content!
Cheers man! 🍻🤝
We normally cut off the old aluminum lugs and replace with the newer copper top style because of overheating connections.
Great video Aaron, the real life faults are always good to watch. That must have went with some bang to distort the door like that. Stay safe. All the best.
Great video
Awesome videos
Great video, Aaron! Thank you and stay safe. 👊👊👊
Great to see ya Alan! Hope all is well 👊👊
Afternoon Aaron. Thanks for another good video from your area. Of course you never tell the actual time length from start to finish, but we all know with logistics and getting crews together to respond that you were into many hours for this transformer change out. Stay safe and spring is on the way.
Working URD in south Florida, pretty cool to see we use the same steps, same material when swapping out a transformer
Nice video! I like cable setups because it's a bit more similar to my home country. Although here, they use mostly complete Ring Main Units instead of such a hard feed-through. This feed through is nice and simple though, I like that.
Back in the early 90s a padmount down the street from me caught on fire. I don't think it blew up, but it was still a sight to see!
Nice job Aaron & the boys for swapping out that bad pad mount. I guess for your facial expression that you don't like direct buried wire & underground. I'll have you know I have paid for a lot of things with underground cable failures.
Don't you love that cross link poly primary wire? 😂 We use the same tools for skinning that wire. We use a torch to soften up that semi con before we remove it. I have seen several "flower pots" blow out of pad mounts. I never saw that elbow with a stud on the wire. That's new to me too.
That looks like a poured in place concrete pad with all the wires jammed up there. We only mark one wire on the secondary side though. Black is the opposite color.
Love your digger truck! Two pistons on the lower boom. A lot more power with that set up. We only use Altec here. The repair guy for them is constantly fixing our stuff everyday.
Beauty!
Thanks
More of these please. Service calls where you need to stop an outage.
I love when customers ask why don’t we bury everything underground wah wah wah. This is the huge down side to underground. It’s almost always a mess. Hours of troubleshooting and hours to repair. Underground outages usually mean no power to customers for hours. Overhead is way easier to troubleshoot and repair. Plus the property damage in order to make the repairs.
Just interviewed for a hydro powerhouse position. I think it'll be a good job in lou of a lineman apprenticeship. I'd detest having to replace urd cable. Sounds like an extended outage & a bunch of hassle, but them lights need power!
Thank GOD you have a Good Brain 🧠 because this Type of Work does Not give you a Second Chance. 🤔👍🙏
👍👊‼️ Late watching this one ! Feel like I should dock myself or something. 😂
Lol!
Glad ya found it tho! Was glad to have been able to capture some of that job. It was rather unplanned lol
Subscribed to Rooted Arborists. Should be interesting.
Things got spicy in that transformer. Years ago, there was a major apartment condo fire in my town, one transformer/service feeding 4 buildings on a common parkade. The padmount doors were shot ~15 feet.
Good stuff bro! Be safe out there. What brand are those leather work gloves your using? Thanks bud
Thanks man! Youngstown, absolutely love them.... Our company tried just about every brand out there!
AMAZING I HEARD THOSE BIG GUYS WEIGH 2000LBS
in the video he said this one was 1,100 pounds. (shipping weight is usually on the outside)
Omg I work for the company that made that new transformer!!!!!!!!! 🙈
I like the new video
Nice job, one question I have is does your utility have a procedure for checking the low voltage side of the transformer for correct secondary voltage before energizing the customers panels? I know it's a pain in the ass... what's your thoughts on how important that step is?
We check voltage before leaving unless there was reason to suspect a problem. For individual installs, we'll check before putting the meter on and for commercial installs typically the main is open and checked before load is switched on.
We don't normally close In a tx on a new install without secondary leads on for a voltage check.(Followed by an open, install and close).
Would that be a bad thing tho? ... Definitely not! Unnecessary 99.9% of the time, but would certainly be an extra step in the right direction.
IMO of course!
16:50 the Canadian accent big when talking to others
I have pad mount in my side yard, very close to my pine tree, and the neighbors bush. My riding lawn mower barely fits between pad mount and neighbors bush. I hit the pad part with my mower deck, scared the shit out of me, I thought I damaged the the pad mount, I figured alarm inside the pad mont box would alert my local utility. Days later they were out didn’t say anything to me, that’s it.
Alarm?
I'd still prefer to change the padmount,than dig up 30m of UG cable.
It looks as if that transformer is ready for the scrap yard.
So did your crew megger the primary and secondaries in the new padmount to see why the cutout fuse blew before they reconnected and closed it in?
Hello from Ireland, just finished viewing "What's in the green box" video. Have a question - on the LV side, are the feeders fused in the transformer? here each phase is and there can be from two to eight feeders. Thanks
Hey! Yes, all of our transformers are fused internally. The fuses are located on the high voltage side and protect the load/low voltage side but not feed through (primary leaving the transformer to feed the next one) cables.
Hey Aaron, what’s the clothing company your company use? Really like the pants.
Hey Aaron, bit of a weird question here but it is atop of my curiosity list. I just got my start in the Linework trade a week ago today! My question to you is the boots that you wear. They look a lot like Keen’s. I believe you even said in one of your videos that you do in fact wear Keen.
My question is, when you’re climbing does your hooks hurt the arch of your foot because there is no steel shank in keens unlike other brands such as Carolina, Thorogood, or even actual “climbing” lineman boot company’s such as Hoffman. I was just curious , I love your vids. They have imparted so much knowledge over the years that I’ve watched. I apply it everyday and it helps me standout as an apprentice.
Really appreciate the kind words!
I find the Keen boots extremely comfortable. I do a lot of walking and driving tho... They don't hurt my feet when I climb, just because I'm used to it.
As much as I love Keen boots, I don't recommend them for everday climbing or those new to the trade.
Definitely find something a little more rigid and durable, at least until you get a feel for the job!
👊🤝
The real question, is did you fix that street light since you were there.
im going to school now
What's the brand name of the semicon stripper and the insulation peeler?
Imagine being near that when it gave up.
If it exploded hard enough to bend the lock, shouldn't there have been vaporised+condensed copper all over the place? I didn't see as much as a scorch mark?
I see a pretty big scorch mark on the wall of the transformer going half way around the socket. 5:13
Random question about power lines and tornadoes... Can you estimate how much force it would take for wind to pull a conductor off an insulator? In most videos of tornadoes I see, there's always power flashes as the tornado crosses a line and pulls the wire off the pole. I'm just wondering how much force this actually takes.
That sounds less likely as debris hitting the insulator hard enough to break it.
@@jovetj could also be lines slapping together. Also, remember that gravity plays a major roll in engineering and storm winds can "lift" which is the exact opposite direction. IOW, unexpected stress in a different direction.
@@rupe53 I just don't see lines slapping together solely responsible for removing them from insulators.
@@jovetj I didn't say solely responsible. The problems with storm related wind is they can go in different directions only a few feet away. IOW, push, pull, twist, up and down. Much different than 100 mph in one direction. Also, sheets of rain can draw an arc over dirty insulators where normal rain might not.
The flashes are usually from the wind slapping conductors together.
Street light stuck closed you mean?
Any guess as to what caused the failure?
I always blame lightning. Can be pretty easy for lightning to damage the windings in the transformer and cause it to pop at a random-seeming time in the future.
What happens if you couldn’t get the car to move, what is your next plan?
Our other two options would be a very large screen to reach from the road or using a backlot machine that can fit in between a 30 inch fence opening
Great video thanks for sharing
I can't believe how people complain about some driven on grass I'd be like do what ever yall want to get thenpower back on
Love it when customers are like this. It makes the job much less stressful. In any case we always do our best to respect customer property.
Why was the street light on at 8:41 ?
As he says at 10:15 the photoeye is stuck open
I noticed that also, and again at 20:55. This might be a combination of LED efficiency, capacitive coupling and cheap construction allowing a few microamps to pass through the LEDs and get them glowing. This so called "Zombie Bulb" effect has been treated in greater detail by Steve Mould: czcams.com/video/1uEmX5XClPY/video.html and ElectroBoom: czcams.com/video/_bgUy6zA0ts/video.html .
Yea there was a bad batch of photo eyes that allow water to get inside and short out the circuitry
@@Bobsdeclineah, I see now
@@coopermorris1778 Stuck closed, you mean.
What's the next new video gonna be?
I might have an depth primary termination coming up soon.... Also a Bluetooth crimper and whatever interesting calls come up during trouble response.
Hey if you make a 6-hour video I'll watch a 6-hour video.
Here in the UK, we do not use small pad-mount transformers for "standard" installations. They strike me as a major risk, if a vehicle hit it, or kids/copper thieves broke into it.
What do you use?
Your thought process is rather misguided.
@@vladimus9749 A local substation 500 Kva or larger feeding onto a LV feeder pillar with fused ways going out to indivdual main cables, services to properties are then jointed onto the main. If you have a ug fault on the LV then an individual phase fuse will blow rather than lose the whole output of the transformer. In the UK we fuse the LV output of the transformer and the HV side is covered either by local HV fuses to the individual tranformer or a breaker for a spur leg.
I'm a linesman in the uk, we have seperate teams for the ug jointing side of work,leaving us to concentrate on the overhead side.
@@neilh2150 Thanks!
