METHOD FOR DETECTING ELECTRICAL FAULTS BY FORMING ELECTRIC ARC IN AIRCRAFT WIRING AND ASSOCIATED SYSTEM

摘要

The invention relates to a method and a system for determining whether an electric arc is present in an electrical circuit (15) of an aircraft. The system includes a sensor (16) that detects a current in said circuit (15) and creates a corresponding sensor signal, a circuit (50) that determines the presence of broadband noise in said sensor signal and produces a corresponding output signal, and a controller which processes said sensor signal and said output signal in a predetermined manner to determine whether or not an arc flash fault is present in said circuit. / P
