Abstract
An aircraft flight line electrical distribution system has electrical conductors connected to a power source and a plurality of service cables are connected to the conductors at service points. In order to provide electrical services to individual aircraft each service cable is provided with a connector plug for connection to the aircraft and each connector plug has an electronic power interrupter for interrupting power to the aircraft when the power in the service cable is either or both exceeds or falls short of predetermined levels of power. The power interrupter compares a sensed signal in the power line to a preset control signal. The compared signals are supplied to a logic circuit which then maintains a power contactor in the power supply line in the closed position when the sensed signal is at a predetermined reference level with respect to the control signal.
