We have to replace some Federal Pioneer, 5kV, bar type CT's, type MIBTR in some old switchgear. I am looking for dimensional info on these CT's but cannot get an outage to measure them up. Would any of you have this (OLD, OLD) info or know of some customer manuals that might have this stuff in them?
Does anyone have a new or used ground fault sensing CT for a Federal Pioneer Electric relay? The CT is rectangular with a 4 x 17 inch window, part number R4-17A. We have had a failure and require one ASAP. Factory delivery for a new one is too long.
Thank you
