METHOD OF FAULT DETECTION IN A CONDUCTOR OF AN INTERCONNECTION NETWORK

摘要

In an electrical power distribution system, line disturbances produce voltage and current travelling waves, or step-change signals, that are phase-shifted 90 DEG relative to each other. A simulation signal is derived from the current step-change signal and is in phase with the voltage step-change signal. The two in-phase signals are combined and compared with established limit values to determine when a fault occurs.
