Thanks for the information, 111R. It looks like the thermal factor will need to be obtained from a manufacturing specification sheet. The C400 standard won't tell me the thermal factor.
Hello all,
How does one find the maximum current rating of a current transformer? Say the current transformer ratio is 3000:5 and it is C400 rated. I know that the CYYY rating is a measure of the CT's performance, but have no idea if I can calculate the maximum current rating of the CT with...
