Help for power regulation

[Craziboyi]

I was designing a power supply from 60HZ using faradays current law. I have used a coil which will give me 100A at primary 1V at secondary. It can go upto 25KA and down to 50A. I want to limit the voltage at secondary at 25V.
At 25KA the secondary will be 200V. This fault current can stay upto 200mS. How can I limit this voltage at 25V across the coil.

I thought of using a MOV or TVS. But the MOV it is rated for 8/20Us and TVS 10/1000us. I dont think TVS/MOV can dissipate 200V to 25V for 200ms. Whether am I correct?

Can please anyone suggest a ccomponent that can do this purpose? Please help. Thanks.

Sorry, but 25KA power supplies are out of my league. I am surprised that you are asking this in a hobbyist forum, since you clearly must be a very high-powered (pun intended) professional to be working with this kind of current.

if you have to ask the questions that you are
then you are not the professional that BobK was alluding to
