发明名称 ELECTRICAL FAULT DETECTION SYSTEM
摘要 <p>An electrical fault detector system (10) detects (16) electrical faults in an electrical distribution system by monitoring one or more conductors (14, 18) and producing an input signal representing one or more electrical signal conditions in the circuit to be monitored. This input signal is processed to develop a first signal representing the electrical current flow through the monitored circuit and a second signal representing signal components in a selected frequency range typical of arcing faults, and which exceed a predetermined threshold. The system also detects (20) ground faults in the circuit being monitored.</p>
