Method of finding faults in a branched electrical distribution circuit

摘要: A PN modulated signal is applied to an end of a network electrical distribution circuit. The produces snapshot trace energy reflected from various discontinuities along the circuit, including fault. Because fault absorbs large part in signal, reflections same branch as but farther input are reduced amplitude. By knowing position branches and discontinuities, such transformers, can be logically determined. If high resistance voltage pulse initially sensed at time when has low because arcing due pulse.
