PROBLEM TO BE SOLVED: To provide a partial discharge measuring device capable of performing partial discharge measurement and calibration, without being accompanied by a power failure.;SOLUTION: The discharge measuring device for measuring partial discharge occurring in electric equipment, is provided with ring-shaped cores composed of magnetic substances through which partial discharge currents flow, secondary windings wound around the ring-shaped cores, capacitors, and electric-circuit conductor side antennas composed of air core coils. Electric-circuit conductor side device portions composed by forming series resonant circuits of the secondary windings, capacitors, and electric-circuit conductor side antennas, are respectively provided in electric-circuit conductor portions arranged at two or more spots to be capacitively united in electric-circuit conductors. A first electric-circuit conductor side device portion out of those, is used as a simulated partial discharge signal receiving portion, and is made to receive a simulated partial discharge signal simulating partial discharge via the electric-circuit conductor side antenna from outside, and a second electric-circuit conductor side device portion is used as a partial discharge detection portion, and is made to transmit a partial discharge detection signal to the outside via the electric-circuit conductor side antenna. By doing this way, calibration of detection sensitivity on the occasion of using the second electric-circuit conductor side device portion as the partial discharge detection portion becomes possible.;COPYRIGHT: (C)2009,JPO&INPIT
