ABSTRACT:
A ground fault interruption circuit has a detector circuit coupled to an electrical distribution circuit load to detect ground fault conditions in the load. A filtering circuit connected between the detector circuit and distribution network comprises a pi-network filter for attenuating common-mode electromagnetic interference and differential-mode electromagnetic interference. The pi-network filter includes three filter portions which together provide a third order filter to attenuate the interference signals at the frequencies of interest.
