Thanks for all the input
RRaghunath, the loads are a 6-SCR bridge that fires to feed an inductive field coil, but if terminated, the feedback from the field reverses and the internal crowbar would fire to duct energy from the field to keep that field voltage down. internal crowbar can fire in...
Fast, open transition transfer switch causes upstream circuit breaker trip on transfer. From transformer secondary currents with lower loads that survive without a breaker trip, I see an open time of about 30ms. Feeding a 45kVA dry, three-phase transformer 480V to 160V AC, 55FLA, for generator...
