Narrative:
During climb, a series of electrical anomalies occurred leading to a rapid divert to ZZZ, us. Chronologically, the cooling exhaust off light illuminated, generator 1 bus-off light illuminated, restoration was not possible by cycling the generator switch or utilizing APU generator both left wing fuel tank low pressure lights illuminated, B hydraulic low pressure light illuminated. During the final 5 mins of flight, the antiskid inoperative light illuminated and assorted flight instruments failed. Circuit breakers popped include: battery charger, fuel tank 1 forward and aft, B electrical hydraulic pump, 28V xfer, 28V ground server, thrust reverser 1, and normal exhaust fan. The irregular procedure admonition to land at nearest suitable was enhanced by the scope of systemic failures. The close proximity of ZZZ constrained a verbal discussion with dispatch and maintenance controller. An emergency was declared with center, dispatch notified via ACARS, a cabin advisory instituted with flight attendants, and passenger briefed. Subsequent landing was uneventful. Kudos to first officer for an excellent performance including superb situational awareness and CRM integration. The pilot diversion guide was helpful to marshal resources at offline station. Air carrier provided very professional assistance. Post flight coordination with dispatch maintenance controller operations, and fodm yielded a continuation to ZZZ2. Flight attendants provided exemplary service to passenger during the 4 hour delay (some elected to remain onboard!)
Original NASA ASRS Text
Title: B737-300 CREW HAD ELECTRICAL ANOMALIES IN CTR CLASS A AIRSPACE.
Narrative: DURING CLB, A SERIES OF ELECTRICAL ANOMALIES OCCURRED LEADING TO A RAPID DIVERT TO ZZZ, US. CHRONOLOGICALLY, THE COOLING EXHAUST OFF LIGHT ILLUMINATED, GENERATOR 1 BUS-OFF LIGHT ILLUMINATED, RESTORATION WAS NOT POSSIBLE BY CYCLING THE GENERATOR SWITCH OR UTILIZING APU GENERATOR BOTH L WING FUEL TANK LOW PRESSURE LIGHTS ILLUMINATED, B HYD LOW PRESSURE LIGHT ILLUMINATED. DURING THE FINAL 5 MINS OF FLT, THE ANTISKID INOP LIGHT ILLUMINATED AND ASSORTED FLT INSTS FAILED. CIRCUIT BREAKERS POPPED INCLUDE: BATTERY CHARGER, FUEL TANK 1 FORWARD AND AFT, B ELECTRICAL HYD PUMP, 28V XFER, 28V GND SERVER, THRUST REVERSER 1, AND NORMAL EXHAUST FAN. THE IRREGULAR PROC ADMONITION TO LAND AT NEAREST SUITABLE WAS ENHANCED BY THE SCOPE OF SYSTEMIC FAILURES. THE CLOSE PROX OF ZZZ CONSTRAINED A VERBAL DISCUSSION WITH DISPATCH AND MAINT CTLR. AN EMER WAS DECLARED WITH CTR, DISPATCH NOTIFIED VIA ACARS, A CABIN ADVISORY INSTITUTED WITH FLT ATTENDANTS, AND PAX BRIEFED. SUBSEQUENT LNDG WAS UNEVENTFUL. KUDOS TO FO FOR AN EXCELLENT PERFORMANCE INCLUDING SUPERB SITUATIONAL AWARENESS AND CRM INTEGRATION. THE PLT DIVERSION GUIDE WAS HELPFUL TO MARSHAL RESOURCES AT OFFLINE STATION. ACR PROVIDED VERY PROFESSIONAL ASSISTANCE. POST FLT COORD WITH DISPATCH MAINT CTLR OPS, AND FODM YIELDED A CONTINUATION TO ZZZ2. FLT ATTENDANTS PROVIDED EXEMPLARY SVC TO PAX DURING THE 4 HR DELAY (SOME ELECTED TO REMAIN ONBOARD!)
