Two 11.5 MVA transformer cores

Two 33 / 11 kV transformer cores awaiting in the oven while the tanks are being rust repaired and waterblasted.
11.5 MVA Dyn 11 50 Hertz

I created this video with the YouTube Video Editor (http://www.youtube.com/editor)

what happened to the trasnforma? Burned? cheers

[RODALCO2007]

@spiritlight9k It will be back in service in about 3 weeks time.

Awaiting rust repair on the tank, and a repaint.

Will make a video if I don't forget.

I was surprised to see the large number of taps, a lot of work in winding one of those. Another surprising value was the high impedance of 18.68% @23MVA 75degrees. I wonder how much of that is copper losses?

[RODALCO2007]

@bjtaudio Sometimes higher impedance in a TX is reduce the fault level, instead of a reactor in series with the output. A phase to phase fault on a 11 kV busbar could do catastrophic damage in a substation.

Thats really nice to see, good vid !

You are the man, thanks for posting.

Much better than silly mot's lol

[RODALCO2007]

@PhotonicinductionArc Thanks, only problem is that you need a power station feeder to run it.

[RODALCO2007]

@Kurtreidable correct.

[johnofe]

That's excellent! I've always wanted to have a good look inside one of these.

[high1voltage1rules]

What a lovely thing of awsomeness!!!!

My god I'd love that!!

Wicked video mate thanx for sharing!

Thumbs up*

[More350Power]

That is no small transformer and to think all of that is submerged in oil when its operating?

@Driv3th3hiv3 Yes these are quality made. Not chinese.

[ElectronicsAtHome]

Those are serious transformers! Big boy's power supply! :)
