600v AWG8 CT control cable how high voltage AC can take?
(OP)
anybody out there saturating CT's from inside relay room? we have 600V AC CT cables and I was wondering how much cable insulation can take since Saturation tests go up to 1200V AC?
any comments?

RE: 600v AWG8 CT control cable how high voltage AC can take?
On CT's driven to saturation, the common failure mode is for the overvoltage to find the weakest insulation in the system. I have seen a set of terminal blocks catch fire. I have seen the connection board on a GE relay drawout case arc over. I would not want to bet on what happens in any given system unless a specific installation of overvoltage protection such as arc-tubes or varistors are installed.
