Abstract: PURPOSE:To realize the measurement of a partial discharge signal after separating it from various types of noises in a high voltage partial discharge test of an electric device, by adding a discriminating logical circuit for each pulse of the detection signal. CONSTITUTION:A discharge test circuit is formed by connecting three detection impedance ZI7, 5 and 6 with an end of them earthed in common respectively to a high voltage power supply 1, a coupled capacitance C2 and the low voltage side terminal of a sample 3 each. A power line 8 is distributed around the discharge test circuit. At the same time, impedances ZI11 and 12 are connected between output terminals of loop antennas 9 and 10 including the capacitance C2 and the sample 3.
