摘要： The present invention is directed to a system for sensing fault current flowing through a person who touches an exposed conductor in a cable connecting a machine to a power distribution center wherein the power distribution center has a number of power cables for connecting a number of machines thereto. Each power cable has a different frequency impressed thereon by an oscillator which frequency is transmitted through an electrical path including the power center if the operator touches the fault. A sensing circuit for each cable is connected in the electrical path and tuned to only the frequency applied to that cable. When the sensing circuit detects that frequency, the sensing circuit interrupts power to the cable. If, for some reason, the sensing circuit fails to interrupt power to the cable, within a selected time interval of less than one-half second, a backup system interrupts power to the entire power center. In order to detect ground faults, the ground conductor in each cable is grounded to the power center's frame through a zener diode bank which is in parallel with a high pass capacitor connected thereto by a preventive resistor. The zener diode bank also suppresses intermachine arcing should two machines touch or come into close proximity. In addition to ground faults, broken ground wires are detected by connecting each ground wire through a preventive resistor to a signal monitor. If a ground wire breaks, the signal monitor for that cable alerts the sensing circuit for that cable, and the sensing circuit interrupts power to the cable.

摘要： A system of protection for an electric power generating system having a poly-phase generator switchably coupled through a generator control breaker to a load distribution bus, wherein the generator output voltage is controlled by a generator control unit which utilizes isolated voltage and current sense signals having a magnitude proportional to the output voltage and current for each phase of the poly-phase generator, the isolated voltage and current sense signals being generated by isolated voltage and current sensors, comprises a first circuit for monitoring the magnitude of each of the isolated voltage sense signals and generating a first output control signal if the magnitude of any isolated voltage sense signal is below a first predetermined threshold. The system further comprises a second circuit for monitoring the magnitude of each of the isolated current sense signals and generating a second output control signal if the magnitude of any isolated current sense signal is below a second predetermined threshold. A logic circuit is included which is responsive to the first and the second control signals, and to the generator control breaker for generating a protective trip signal for de-exciting the generator and opening the generator control breaker. Preferably, this signal is delayed for a predetermined period of time which is set to a value based on maximum generator output voltage and applicable standards for abnormal voltage transients to ensure that the standards are not exceeded by the maximum generator output voltage.

摘要： 400 Hz aircraft ground power supply with a three phase AC power source connectable via an electric power relay and flexible cable provided with a socket connector to a plug connector at the aircraft. In the energizing circuit of the power relay is arranged a closing contact of a second electric relay, the energizing circuit of which is led via switching means at the socket connector to be actuated by a pin of the plug connector. Thus the closing contact of the second relay is opened as long as the socket connector is not plugged to the plug connector. A third electric relay energized via the connectors by a source of DC current on board the aircraft has a closing contact in parallel to the closing contact of the second relay in the energizing circuit of the power relay and further opening contacts disconnecting a separate source of voltage in the energizing circuit of the second relay if the third relay is energized.
