A detector system for precursively identifying an electrical arcing event is provided. The system may include a transmission channel for transmitting a radio frequency signal to a zone where an arcing event may occur. The system may further include a reception channel for receiving a radio frequency signal resulting from an interaction of the transmitted radio frequency signal and an electric field which forms at the zone as a precursor to an arcing event. A pre-arc identification circuit may be coupled to process the resulting radio frequency signal. The identification circuit may be configured to generate a signal indicative of a pre-arc condition based on at least one parameter of the resulting radio frequency signal.
