motor excitation panel
motor excitation panel
(OP)
This question is wide, but i require help.
We have a compressor motor for which there is an excitation panel. It is connected with PLC system.So our system is Dual channel Digital Excitation system. We have two channels A & B. Normally channel A is kept selected.whenever we start the compressor channel A trips & Channel B takes over.We checked all the contactors but none was damaged. I know there can be many reasons, but any experience will be welcome

The problem may be as simple as a failing breaker, or possibly reversed polarity on channel "A".
