WHAT'S INSIDE a Pole Mounted Distribution Transformer

A WARNING:
The older distribution transformers (pole pig) oil contain a very carcinogenic chemical called PCB or
Polychlorinated Biphenyls. Please be careful and wear appropriate PPE

A couple of factoids that many people dont know.......The high voltage wire which runs from the overhead line, into the primary coil....exists the primary coil and runs down the power poll into the ground!!!!!!!!!!!! and there is no direct connection between the primary coil and the secondary coil. The step down voltage is achieved by the number of windings and by induction through the steel core. Cool stuff!~!!!!!!!!!!!!!!!

i was surprised by all the oil inside the transformer case. i had no idea.

I've known about transformers since I was a small boy with a toy electric train. And, living in a rural setting, I've been curious about pole transformers and what was inside. They come in so many sizes, from small, residential, to huge sub-station units.

Awesome video thank you!

Breaker company name send

How many windings does each coil have?

you dint let me see all. the parts in transformers

The oil is good to cook food ?

That's so cool! thanks for sharing. I love transformers, it great to see how they're from inside.

WoW

Sir, I would like to ask if this transformer is damaged, let's repair it again

Can you take it even further apart? As in take out all of the components, disconnect everything and lay it all out?

Thank you! I just started a job building these transformers. I do the internal winding. It was very helpful to see the finished product as everything else is built on another site.

Breaker size in transformer?

Hello! Sir, I'm a new subscriber, I'm just asking, what is the use of oil inside the transformer?

I'm curious, in places that base their rules on IEC standards or BST standards what is the tap limit for service transformers? In the US it's six for utility owned transformers, and ONE for the same exact transformer if it's customer owned.

It beautiful inside the transformer

The transformer looks old asf. It might contain pcb’s

What are the bushing purpose. Allow voltage bleed or suppress it. Suppress the bleed, well allow dissipation without Corona arcing???

Thanks for the video Sir, do you know how much the transformer weighs and approximately how much copper weight will be there in the transformer. Cheers from Sri Lanka

Nice explanation

Is that transformer inactive or is it active

Excellent video, exactly what I was looking for. Thanks

Other countries never heard of speed ratchet wrenches??

Don't these have pcvs???

So fantastic transformer in side.

At one minute and 46 seconds it's just the gasket you know I LOVE IT !!!

Thanx 👍

🥴🎤 I like how he’s got echo and reverb in his talking. 🎙! 😑

Very interesting how one thin wire goes in at the top and three thick wires come out at the side..

Ok thank you

Baut brapa tu kang

im newbie to your channel...sir can you explain or make another video that you take out the rolled sheeted thing inside the transformer and labelled one by one...this video helps me but i need more and specific...thank you...from philippines..godspeed👌👍👌

Excellent...usefull video. Thanq for uploading...

Thank you

I thought that was liquid from leaked case, never thought such things need coolant agent, how many degrees for a powerful throttle or maximum electricity supply could raise the temperature?

Nice content brother!
