Abstract

PURPOSE: To detect inside partial discharge with a transformer, etc., connected to an air transmission line by fixing a delay time so that an input from a detection terminal part of a transmission-line side after passing through a delay circuit will be in phase with that from a transformer-side detection terminal part.
CONSTITUTION: A 1st input such as a corona signal, etc., of a transmission line is supplied from the capacitor terminal of air bushing 6 to differential amplifier 13 by way of coaxial cable 10 and delay circuit 11, and a 2nd input is 1ed from the capacitor tap of gas-oil bushing 4 to amplifier 13 via coaxial cable 12. In this case, two inputs to amplifier 13 are put in phase by circuit 11. On the other hand, inside partial discharge pulses generated by the transformer are applied to cable 12 and also to cable 10 and circuit 11 via gas insulating airtight switch 5. Therefore, two pulses are outputted without being canceled and then displayed by display unit 14.
