power transformers to cat vr6 are blowing up
(OP)
Hello I have a cat generator that the ct's are blowing up that feed the vr6 voltage regulator. The voltage that feeds the transformer from the generator is 60 volts.

CTs are blowing up?
You feed your CTs 60V from the generator?
And somewhere along the way we also have exploding power transformers?
Would you mind dropping some of the drama and give some facts?
Low voltage CTs on the whole do not blow up.
CTs typically don't get fed from a voltage source; that's something you would use a VT for.
Where on the generator are you getting 60V?

If we learn from our mistakes I'm getting a great education!

First, go to www.baslercom, download a copy of manual for an AVC63-13, commercial version of VR6 and a better manual than CAT's in my opinion.
Properly indentify component feeding the AVR and please more completely describe the failure mode. Only one CT used with a VR6, and it's optional, the droop CT. Is this a retrofit or did gen come with VR6 from factory? Sometimes in retrofits the droop CT circuit got left open, with an occasional failure.
What voltage is your machine? How old? What application? Better info will get you better answers.
