IV. PREVIOUS SIMILAR EVENTS
There are no previous HNP trips related to a failure the main generator neutral ground protection relay.
V. CORRECTIVE ACTIONS
Completed corrective actions include replacing the failed relay module in the main generator stator ground detection circuit. Additional corrective actions are to establish specific inspection requirements for the generator, main transformer and auxiliary transformer protective relays and to brief appropriate maintenance personnel.
