EVENT _98:5 CAUSE:
An equipment fault caused the loss of all Non-1E 13.8 switchgear due to incorrect tap settings for the instantaneous overcurrent relay for breaker 2 NAB 03. This caused a Turbine Trip / Reactor trip when the main generator output breakers opened.
I CORRECTIVEACTJON: Reworked the incorrect tap betting on the overcurrent relay. Performed a broadness review of protective relays, bus transfer scheme and other relay settings. Repaired the turbine bearing (discovery item after trip).
CRITICALPATH WAS:
Disassembly and reassembly of turbine bearing U.
