Abstract

PURPOSE: To eliminate the noise during measurement of the discharge of a cable and accurately detect partial discharge pulses by supplying the output of a polarity discriminator to an unbalance detecting circuit and controlling the gate to a measuring device by means of the detected output thereof.
CONSTITUTION: An umbalance detecting circuit 10 of magnitude is connected to a polarity discriminator 7, and the detected output thereof is supplied to the gate 8 for a measuring device 9. When a large partial discharge pulse is generated in a cable (a), for example, the pulse voltage of the same polarity is generated in detecting impedances 5a, 5b, and this causes the gate 8 to turn off. Next, when an unbalance is detected in the magnitude of the polarity with the circuit 10, the gate 8 is turned on, and the partial discharge pulses are measured.
