We installed 3000 HP, 12 pulse digital controlled thyristor system. 2 bridges are in parallel. Common transformer with 2 secondaries are feeding input voltage of 1000 vac.
While motor is loading, we found there is a difference of @ 50 V between 2 secondary and heavy distortion in both ac inputs. Can somebody explain why this is happening and how to overcome it?
