Single-sensor microcontroller-based approach for ground fault circuit interrupters

Single-sensor microcontroller-based approach for ground fault circuit interrupters

A microcontroller-based temperature compensated circuit for ground-fault circuit interrupter to meet requirements of UL 943 using a single sensor (T1) to detect both ground-fault and grounded neutral fault conditions in both full-wave (CR1) and half-wave AC power supplies as part of a ground-fault c...

Zusammenfassung:A microcontroller-based temperature compensated circuit for ground-fault circuit interrupter to meet requirements of UL 943 using a single sensor (T1) to detect both ground-fault and grounded neutral fault conditions in both full-wave (CR1) and half-wave AC power supplies as part of a ground-fault circuit breaker (10) or a receptacle device.
