Power supply for ground fault circuit interrupter |
摘要 |
A ground fault interruption circuit detects a ground condition associated with a load in an electrical distribution system and disconnects the load in response to a ground fault condition. The circuit includes a ground fault detector connected to receive a ground fault imbalance signal and operative in response to a power signal, having specified voltage and current levels, to provide a trigger signal to disconnect the load from the system when the imbalance exceeds a certain level. A regulated power supply circuit a substantially constant current and voltage signal to the detector to minimize excess power to the detector and heat loss. The power supply includes a start up and storage portion and a constant current supply portion.
