Testing Rectifiers and Load Share
Testing Rectifiers and Load Share
Step Action
1 Turn all rectifiers to STBY.
2 Connect a resistive load box (proper voltage) to the system’s
positive and negative bus bars.
3 Verify that the system load is less than 50 amperes.
4 Increase the system load to 50 amperes.
5 Turn ON all the rectifiers; after approximately 60 seconds,
verify that the load is divided equally among all the rectifiers
(within 2 amperes).
6 Reduce the system load. Verify that the rectifiers continue to
share the load.
7 Remove system load.
