Summary:PURPOSE: An ultra-high frequency partial discharge array sensor for a high voltage apparatus is provided to measure discharge signal and the location of internal defects by integrating a high sensitive sensor for the discharge signal and an array sensor. CONSTITUTION: A sensor(110) detects electromagnetic wave partial discharge signal which is generated from internal defects of a high power apparatus. The location of the internal defects is simultaneously detected. A surge preventive filter(140) prevents surge from the sensor. A signal time delay regulator(150) regulates the delay time of the signal. A signal switch(160) selectively transmits or blocks the signal from the signal time delay regulator. A connector(170) connects the signal from the signal time delay regulator to the outside.
