Abstract
PURPOSE:To periodically and easily check the calculation function of a partial discharge generating position, by providing an operation checker for imparting a dummy discharge pulse and a dummy ultrasonic signal to a locating part. CONSTITUTION:An operation checker 21 consisting of a dummy discharge pulse generating part 23 and a plurality of dummy ultrasonic signal generating parts 24 is provided and the single pulses 24a-24d corresponding to discharge pulses are injected in the input terminal of the locating part 11 of an in-oil partial discharge monitor apparatus. The time detection circuit 17 of the locating part 11 stores the time corresponding to each of the single pulses and a position calculating part 18 performs the location of a three-dimensional position based on a radar method to display a location result on a display part. By comparing this location result with the calibration data of a predetermined partial discharge generating position, a locating function is simply checked.
