PURPOSE: A system for measuring a position at which partial discharge occurs in a power equipment is provided, which compares polarities of partial discharge signals detected by at least two partial discharge detectors and senses a difference in arrival time of the signals, to measure a position at which partial discharge is generated in a power cable and accessories. CONSTITUTION: A system for measuring a position at which partial discharge occurs in a power equipment includes at least two partial discharge detecting sensors(3a,3b,3c), an amplifier(4) connected to each of the sensors to amplify a partial discharge signal transmitted from each of the sensors, and a partial discharge signal display(5) for displaying the partial discharge signals sent from the amplifier, simultaneously.
