Incident Description
During the climb out from runway 26L at approximately 200 feet, the number 6 display unit on the pilot's instrument panel went blank and the engine alert display showed a left generator off alert. The first officer requested radar vectors from the Atlanta Tower. After contacting the tower, the airplane experienced a complete electrical power failure, and communications with the Atlanta Tower were lost. Emergency electrical power was restored shortly after the failure. Flight attendants then advised the captain that there was smoke in the aft part of the cabin area. The captain and first officer reported smelling an electrical burning smell and declared an emergency. The captain returned to the airport for an emergency landing and evacuated the airplane on runway 9R.
Examination Findings
Post-incident examination of the Power Conversion Distribution Unit revealed that the tantalum capacitor and the permanent magnet generator input transformer had failed. The failed transformer was identified as the apparent source of the smoke in the cabin. No other anomalies were reported by the captain.
