Abstract: An apparatus detects a ground fault of an exciting circuit and a field circuit of an AC exciting variable speed rotating machine.  The exciting circuit outputs an excited voltage controlled a frequency and/or an amplitude, and the field circuit of the AC exciting variable speed rotating machine is applied a field current by the excited voltage of the exciting circuit.  A ground resistance is connected between a neutral point and a ground.  The apparatus detects a current flowing from a ground to a neutral point through the ground resistance, and detects the ground fault based upon the detected current.  Therefore, the apparatus can detect a ground fault of a field circuit and an exciting circuit of an AC exciting rotating machine during the AC exciting rotating machine operation with certainty.

Title: Arc fault detector with immunity to tungsten bulb burnout and circuit breaker incorporating same
Inventor: RAE THOMAS CHRISTOPHER
IPC: H02H1/00
Filed: 1998-09-28
Granted: 2008-12-23
Abstract: A circuit breaker with an arc fault circuit provides immunity to false trips caused by tungsten bulb burnout and by a cold tungsten filament energized through a solid state dimmer. The detector circuit includes a pulse generator which generates pulses in response to the step increases in current occurring each time an arc is struck. A zener diode limits the amplitude of pulses generated by the pulse generator to a value which is below that of pulses generated by the tungsten lamp. When a time attenuated accumulation of these pulses reaches a predetermined value, the circuit breaker is tripped. By clipping the pulses with the zener diode, the few large pulses generated by tungsten bulb burnout or energization of a cold tungsten bulb by a solid state dimmer switch are insufficient to allow the time attenuated accumulation of pulses to reach the trip value.
