Latest Patents
David C Randolph holds a patent for a "Ground fault interrupt circuit apparatus for 400-Hz aircraft electrical." This resettable ground fault circuit interrupter is specifically designed for use with 400-Hz aircraft electrical systems. It interrupts the AC power between an aircraft electrical system and one or more electrical appliances when a ground fault occurs. The circuit utilizes an imbalance sensor, implemented as a multi-turn coil of a transformer, to detect ground faults. The signal generated by the coil is amplified and applied to a thyristor, which determines the circuit's configuration for interrupting or allowing the AC signal. Light-emitting diodes indicate the interruption status, and a reset switch is provided to restore functionality after a ground fault is resolved.
