150A SMR
Rectifiers
For Lineage Power J85702E-series (150A SMR) rectifiers an RFA may
be generated by using the following procedure:
Step
Action
1
Set the rectifier to the Single Power Module Assembly
(PMA) Fail option by placing BGB SW100-8 to OPEN.
2
Set the Output CB switch of all three PMAs inside the
rectifier to the Off position,
3
Raise the rectifier voltage (measured via the rectifier voltage
test jacks on the front panel of the rectifier) above the
Backup HVSD level for the rectifier (set via
SW 100-6/7 on the BGB display/control card of the
rectifier).
4
Verify the RFA in the controller.
5
Lower the rectifier voltage once again to plant float and
restart it to retire the RFA.
6
Close the PMA Output CB switch of all three PMAs and
verify normal rectifier operation
Note: Load share should be disabled (BGB SW100-5) anytime rectifier
voltage is adjusted in these rectifiers with the PMA Output CBs closed.
