03/15 1515 Fault on switchyard breaker caused breaker to open creating electrica' transient to Condensate Polishing System resulting in condensate /feedwater transient. At this time Heater Drain Pump was intentionally shutdown to cause a generator runback in order to stabilize the transient. Power

educed to approximately 70% to repair minor damage. Repair included replacement of bearing on the hector drain pump.
