Narrative:
Experienced loss of all electrical power on takeoff roll at 120 KTS (V1 = 141 KTS). Rejected takeoff, exited runway and ran checklists. After visual inspection by ground crew, we taxied to the ramp. Callback conversation with reporter revealed the following information: the reporter stated maintenance replaced a #1 generator relay and a bus tie control panel and deferred the #1 generator per the MEL. The reporter said this was a high energy stop and after the brakes cooled, the aircraft was dispatched. The reporter stated that he was uncertain if the standby power was switched on and operating.
Original NASA ASRS Text
Title: A DC10 REJECTED TKOF AT 141 KTS DUE TO LOSS OF ALL ELECTRICAL PWR CAUSED BY GENERATOR, GENERATOR RELAY AND BUS TIE CONTROLLER FAILURE.
Narrative: EXPERIENCED LOSS OF ALL ELECTRICAL PWR ON TKOF ROLL AT 120 KTS (V1 = 141 KTS). REJECTED TKOF, EXITED RWY AND RAN CHKLISTS. AFTER VISUAL INSPECTION BY GND CREW, WE TAXIED TO THE RAMP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED MAINT REPLACED A #1 GENERATOR RELAY AND A BUS TIE CTL PANEL AND DEFERRED THE #1 GENERATOR PER THE MEL. THE RPTR SAID THIS WAS A HIGH ENERGY STOP AND AFTER THE BRAKES COOLED, THE ACFT WAS DISPATCHED. THE RPTR STATED THAT HE WAS UNCERTAIN IF THE STANDBY PWR WAS SWITCHED ON AND OPERATING.
