These will be based on the load (ie the metering that you are going to use it)

If your meter is 110V then put the CVT at 132000/110

and similarly do it for CT.

BTW - do it under expert guidance- don't try to do it yourself- you are playing with explosive situation, and I am not sure you are qualified.
