Static Exciter Field Cables
Static Exciter Field Cables
(OP)
I was recently told that the field cables for Static Excitation Systems need to be rated for 10 time (10x) the max exciter voltage... is that true?... is it in an IEEE Spec somewhere?
For example, I'm spec'ing a cable a for a static exciter field run that will have 240 V (nominal) and 360 V (max). Do I need a 4 or 5 kV cable?
I've looked in my IEEE standards, surfed the websites of cable and exciter manufacturers, and searched on Eng-Tip but to no avail.
Any help will be appreciated.
Thanks,

I'm kind of curious where the 10X transients would be expected to come from...?

The crow-bar circuit should stop the worst of the over voltages that might occur.

This could account for the test level rating of your exciter cable, which is a part of the rotor circuit.
