PWR SOURCE FAILURE TO THE FACILITY. UPS FAILED TO CARRY THE LOAD DUE TO A TRIPPED BREAKER. NO COM AVAILABLE INTER INTRAFAC AS BATTERIES NOT CHARGED.

Narrative

ON JAN/XX/96; AT APPROX XA30; A TRUCK HIT A LIGHT POLE KILLING ALL PWR TO TUL. THE (UPS) OR BACK PWR FAILED TO ASSUME THE LOAD DUE TO A TRIPPED BREAKER; THEREBY RENDERING THAT PWR SOURCE UNUSABLE. WITH NO BACKUP PWR TO ESSENTIAL SYS LIKE THE ARTS; FDIO; ICSS COULD NOT BE RESTORED. COMS TO AIRBORNE ACFT AND INTER/INTRAFAC WAS NOT FULLY RESTORED FOR APPROX 41 MINS. THIS SIT HAD DEADLY POTENTIAL; HOWEVER; THERE WAS NO LOSS OF SEPARATION. THIS SIT COULD EASILY BE AVOIDED IN THE FUTURE IF CERTAIN ACTIONS ARE TAKEN. TULSA IS VERY UNIQUE IN THAT WE HAVE 2 SEPARATE PWR SOURCES COMING TO THE FACILITY (A N FEED AND A S FEED); HOWEVER; THE N FEED IS THE ONLY ONE THAT FEEDS PWR TO THE (UPS). THE FAA NEEDS TO CORRECT THE S FEED TO THE UPS ALSO GIVING US 3 INDEPENDENT SOURCES OF PWR. ALSO BACKUP RADIOS WOULD NOT WORK BECAUSE THE BATTERIES WERE NOT CHARGED! AND THERE WAS NO WAY TO COMMUNICATE WITH THE TWR. WE NEED DEPENDABLE BACKUP RADIOS OR AIRWAYS FACILITIES NEEDS TO QUIT CUTTING ITS WORKFORCE SO DEEP THAT THEY CAN'T DO ANY MORE PREVENTIVE MAINT AND MAYBE SOME WALKIE TALKIES TO COMMUNICATE WITH THE TWR DURING PWR OUTAGES.
