My husband used to work for a school system that a large majority of the schools had transformer vaults with pole type transformers sitting on the floor or on racks. That was the norm back in the 50’s and 60’s and even early 70’s. They had a football stadium with two transclosures. One took the 12,470 down to 4160, and the second took the 4160 to 480. The utility was responsible for the 12,470 enclosure, but the school system was responsible for all the 4160 stuff.

Aaron! I had no idea you had a channel! I used to work with this guy!

When I was in Puerto Rico they had 3 phase dead ended on a building and feeding a transclosure with to transclosure lol. Literally 3 phase primary 4kv dead ended on a cinderblock wall. And open delta bank pole mounted transformers sitting on the ground. No enclose except for a broken 5ft Chain link fence around it. Anyone can walk in there and grab primary etc. I said to my boss are we energizing this or should we isolate it. He said that’s been energized for 30 years like that, heat it up👍 place was wild brother

Don't worry about not posting frequently! Those of us that truly love this content will be here for the next one, even if its a year from now.

I remember one of those located behind a business I worked at about 30 years ago. There was a pole fire across the road and something went horribly wrong. I didn't see it, but I heard it. One door was actually blown off and across the parking lot. No one was hurt. You will be about an hour and a half drive from me. I hope you enjoy your trip. Thank you for taking the time to post another interesting video. Please stay safe, and God bless.

That box needs to be replaced for sure what a eye sore wow

In 2017 I worked for a financial service company and we decommissioned a Wells Fargo branch in Miles City, MT and they had a vault in the basement that had been welded shut so per the SOP we had to open it and confirm it's empty and disable the lock, upon cutting the door and opening the day gate we found it was converted to a transclosure in the 60s and long story short back in the day they cut a hole in the 1920's brick and installed a man door with a hasp so if we would have skipped ahead a few days we would have cut a padlock vs a vault door. Needless to say we crapped ourselves when we noticed. The power company didn't know, CBRE the building owner didn't know, and of course Wells Fargo didn't know. That transformer bank also fed several other large commercial properties. I don't remember seeing any CTs so not sure how they metered. I feel sorry for the gents who get to deal with the PCBs and haul them up the narrow stairs.

I remember as a kid I would walk by these huge boxes and just think for hours what could possibly be inside them. That was back when running all over a city exploring was the only thing you could do.

The buildings you show in de beginning kind of reminds me on good old East German "Plattenbauten". Fast to build houses for many families made from concrete panels

I have been honking support for our striking hydro workers here in Ottawa.

A school I work for built in 1961 has a dedicated transformer "vault room" built into the building. It has three pole mounted transformers just sitting on concrete in open air. That was the first time I've ever seen anything like this. The maintenance staff mistakenly cut off the door padlock and once we opened the door and realized how dangerous it was we called the electric company to put a new lock on the door. The "fireproof" wall and ceiling of that room doesn't instill a lot of confidence in me. All of the secondary feeds passed thru the cinderblock wall into the back of the MDP in the boiler room.

I was sent to Key West in September 2017 to help restore power on all the Navy and Coast Guard bases there. On the Coast Guard Station I encountered a transclosure. It had 6 transformers in it. Each was a 167-kva. They had primary UG elbows on the tops of each primary, instead of the normal open wire connection. The base was still without power but when I oped that thing up and saw that, I took several pictures of it and closed it up. I told them hope for the best when we hot this place back up. The station commander said he hopes it blows sky high. He wnts it gone but no money in the budget. Storms are good sometimes for system improvement. But unfortunately this time when we made other repairs and closed in the main incoming feeder, it held just fine. Oh well, there will be other storms I told him. Bottom line for me was get rid of that thing and get a padmount transformer. Looked like a trap from the movie Saw to me.

One summer during my engineering school years, I worked for an electrical construction contractor which worked for the local electric power utility in the Black Hills of South Dakota. I assembled 3 or 4 trans-closure cabinets as well as several URD underground rural distribution 13 kV primary switching cabinets with the elbows and parking sockets. Another nice video. Keep it up and remember to "point with your elbow" when you have to work close to an energized part. Best wishes from Iowa.

You guys deserve a vacation big time.

I really like your explanations of how and why your grid is so totally different than our Dutch grid.

The municipal system where I live still has a few scattered transclosures and which are likely holdovers from when they had 2400 delta primary (all long since converted to 13.8 Y). I also remember seeing a modern version on a coop system that ran 24.9kV, but this one was specifically for primary metering. It gave me the heebie jeebies looking into the enclosure knowing I was just feet away from energized BARE conductors carrying line voltage! Even my supervisor on this trip was VERY cautious as he inspected the setup to confirm the high-voltage conductors were correctly routed from the incoming potheads through the instrument rack to the outgoing potheads.

That’s a first for me! All lineman never stop learning but I never heard or saw a “transclosure”? Thanks Aaron. 👍🏻👊🏻

Glanced at the title and picture and thought "A goofy name for a shipping container?". Then I saw it was you and put it in the right mindset. lol

Hi I would have thought that those separate transformer on the pole should be replaced with one large pad mount transformer much safer.

Appreciate you filming this type of information - as a commercial engineer designing 480V and below systems, it's nice to see what you utility folks deal with on your side of the transformer!

I'm a new apprentice but when I was going to school I interned for a small town that had 4 or 5 active transclosures. Their pretty spooky when you open them even when they deenergized you can feel how dangerous they are.

Hi Aaron. That's a unusual application for sure. Can't wait for you to show us all the new tools.

Oh boy “Bob”…, you don’t know the comments that you are gonna get with this video title…. hahaha..! Great video, Thank you sir.

Man, a metal shed with three trannies inside, looks well scary and a death trap but I suppose you would isolate them before opening it up. I hope the rusty old box in the video is earthed. In the uk we have pad mounted TXs with cable entry boxes so there are no exposed parts. Also we would have a single 3phase TX instead of three separate ones. Different country different ideas. Nice informative video man, keep them up.

I did engineering on a couple of old schools with aerial transformers in a vault. Problem was they had very high fault currents >100k. Always has to spec fused service disconnects.

I learn something interesting from all your videos. Please keep them coming. And thanks for keeping our lights on!

Have fun in Milwaukee! Very underrated city, I enjoy living here.

I remember seeing some at MacGregor Point Provincial Park, in Ontario that if they are still there would be about 50 years old.

Hope you had a good vacation brother, you damn sure earned it.

What is your company procedure for encountering a Decepticon in one of those transformer enclosures? Is there a number to call to get Optimus Prime to respond?

Wow, i grew-up right up the street from there! I see they're finally building an apartment on that vacant lot; it always surprised me it sat empty for so long. Love your channel, I'm an Electronics Technologist by trade since '93, much respect for what you do! Cheers :)

I love Milwaukee tools! That will be an epic trip. I’m a month in now as a ground man down here in south Florida and love it.

I've dealt with a transformer room with the local utility so they could clean the space and gather oil test samples, that was a cramped space, I can't imagine the tight clearances there would be in a transclosure.

Good to have you back, Aaron! Hope you had a great vacation. Hoping to head up to Nova Scotia this fall.

Oh Yeah! Great to see you again. I always look forward to seeing your videos.

I did engineering on a couple of University buildings to remove aerial transformers that were inside the building electrical rooms. Very scary to go in those rooms with exposed transformers. Apparently common practice back years agol

Good content...I certainly enjoy your channel. I'm the substation foreman for a municipal electric company. We actually still have a lot of these transclosures in our area. One of the substation crew's regular jobs is opening up and inspecting them on a regular basis. Some of them are definitely a little scary.

Love your content thanks for all the smoke Lol Boston

Good to see you back.

This is going to be a fun job

That is the first one I've ever seen glad you posted it on KZfaq

I live in BC lower mainland. Our linepeople (BC Hydro) out here hang their old hardhats on one of the phase lines to signify that they have gone from jouneyman (green) to lineman (white). They also hang their white hardhat when they retire. Do you follow that tradition out there on the east coast ? I enjoy your channel. Suscribed & always a thumbs up

Do you guys also transfer over the telecom lines? In Quebec the remnant of the damaged pole is left behind (securely strapped to the new pole) until the Bell/cable crews arrive to move them.

Good to see another video thanks again!!!

It's always a fun time when one side says what are you talking about and the other side is standing in front of the dang thing 😂

Glad your ok Arron becarful

I remember way back about 13 or 14 years ago I was helping my nephew at a warehouse in a small town near where I live and in that building there was a room about the size of a small bedroom that had the primary wires going inside that room and there were transformers in there and they were pole mount ones just like the ones in the photos you showed anyways I was just walking around the building and exploring it a little bit and the door to that room happened to be open and I just peeked in I didn't walk in there of course for obvious reasons but man those transformers were huge especially up close I was probably 25 feet or so away but still they looked huge. I think it was possibly 3 phase but I'm not sure I can't remember the number of wires that went into the building but I do know it was at least 2 primaries and it had through pass insulators and I also believe it had cutouts in that room if I remember right.

Привет! Я из России смотрю твои видео через переводчик) Очень интересно как все у вас там устроено, у нас совсем все по-другому)

I was aboot to say, that's definitely oot of date. None the less, good to hear you & the family are good!

9:20 glad you all are safe!

awesome channel

Ask Milwaukee to make a battery assisted extendo stick! My shoulders will thank you!

Wow ❤❤

Super interesting. Thanks for taking the time to show us the insanity from the past.

Love your posts

Tti makes some good stuff. If i wasnt stacked with the Ridgid tools and drive Saabs id upgrade to the Milwaukee linup for sure. Lol

Always a great video thanks for sharing had one of the best watermelons I’ve ever had found a farm right down the road from my house good ole Indiana melon yummy 🤤

Was the pole fire in Dieppe? We had an outage at my house in the afternoon that day and I noticed a crew nearby with a bucket in the air. Afterwards, I went for a ride in the evening and came up on the other scene with the pole cut off. I passed by once and wasn't sure what had happened but when I came back through later, I realised the curve of the road was pointing directly at a fresh pole.. someone obviously had a bad day. It's funny because seeing the amount of people around made me wonder if you were on site. Guess this answers my question.

I'm surprised that box is quite the eyesore.

I used to live in Milwaukee WI on 35th and wi ave in 2004

transclosure...when i finally get all my operations done ...lol

I would think the rust is a hidden hazard

Haha, I know exactly where that it, Awesome neighbourhood, hahaha

And our company is going back to these, because of the difficulty obtaining pad mounts.

At least the busy day did not come with 3 ft of snow!

I was expecting a strange padmount transformer

Wow those things are big to only house 3 singe phase transformers.

Yeah just focus on your job and don't worry if you can't post videos. Not staying focused on the job at hand is how mistakes happen.

👍👊

Have you seen the smoke from the big fire I live in NEW JERSEY I can't believe it traveled that far

I was a little confused when you said that the apartments get 2 of the 3 phases. People often confuse 3 phase power from residential split phase. Most of the world's power companies deliver a single phases 220-240 volt. In North America we use a single phase that is split into 2 inverted 120v phases. They technically are the same phase because they are 180 degrees to each other. This is why you can use a 220 v appliance by wiring them together. If they are 2 of the 120 degree 3 phase power would cause a big light show. So a apartment will get a pair of 1 phase lines. You can see there are 2 of each color. On the pole there are 3 transformers with 3 wires each. The central tap neutral and the two inverted splits. 0:04

Is a transclosure a circuit breaker that identifies as a cut out fuse?

Do you use or work on any single wire transformers?

I wood like to see you doing stuff get a camera holder

question regarding working on power lines, when you call the substations or whatever to de energize lines, who's responsible for that? what if another worker notices it's off, assuming it was by accident or something, energizes it back on? or what/how do they control the lines?

If I was in charge I'd get rid of that dinosaur all together, it's so rusted it's practically falling apart,it'll just get more dangerous as time goes forward.⚡⚡⚡

Stop at the safe house in Milwaukee

"Pole mounted transformers on the ground". That's just sounds wrong for starters. That looked like one crusty old box. I guess trenching in a new line would be significantly more expensive than replacing the box with a vault.

All that splicing in a snake nest - I would have preferred to have proper switchgear in a small housing to make it easy to cut off the power just to the right consumer and also add new consumers without too much trouble.

why would you install porcelain insulators on a new pole?

Ive sent you some links and stories to your Facebook

How about a How To Video on How to Hook up Free PoweR............haa

You Remind us how Dangerous Electricity is and if you Disrespect it, you will Pay the Ultimate Price. Thanks for keeping Safety # 1 so you can go Home to Family. 👍🙏

Yes would much rather see the broken poles putting in etc please thanks

I spoted somthing not good in that box ... did you spot it mr line man 😊

1st comment aboooooooooot 7 min old

Boo 👻

Here I was just thinking it was confused about its gender

Not gonna lie. I'm transgender and my idea of a Transclosure is veeery different to that in this video.. And cue the jokes.. Just remember. I've probably heard them all before.. 😁

If you answer the question wrong about the transclosure it means you're not inclusive

Pole pigs sitting on concrete, can you say dangerous? Glad they don't do those no more. Easy way to cause major issues and electrical fires and arcing. (facepalm)

too lazy and cheap to just do it right and get away with THE BOX LMAO....

It’s something open that has decided to transition to being closed. Geez it’s 2023 “Trans” in any word means you can be whatever you want. Bahahaha

trans...closure gender portation former sistor slate .....😌
