Isolating Motors On One Phase From PLCs On Another Phase
Isolating Motors On One Phase From PLCs On Another Phase
(OP)
If I have a 208VAC AB phase (from a 3 phase supply) powering five 220V motors, is it best to have a step up transformer or just go ahead and use an isolation transformer rated at 208 Or 220 – between the motors and where they tap off of the supply phase. The main reason I’m doing this is to prevent motor surges, etc. from affecting PLCs on the BC phase of the source supply.
No one at other sites I have visited seems to be able to answer this.
