Default A help with an soviet transformer.

Found this today. Do you know what it represents ?

I measured all the solder spots, but no more than several ohms.

They used 400 Hz power on their ships and submarines. It makes for very small (equals lightweight) power transformers at a given VA rating. Unfortunately, you can't run these things on 60 Hz AC unless you de-rate the thing a lot. For all practical purposes, that transformer is useless.

I can use the secondary side as primary like a step up transformer with the aid of a push pull oscillator.

I just need some auto batteries.

If you have 3 they might be used to step up a car alternator.
