Summary:PURPOSE: An ultra high frequency partial discharge and discharge position measurement device is provided to find the location of a partial discharge in real-time by processing only signal detected from a sensor in an ultra-high frequency band. CONSTITUTION: A partial discharge sensor(110) detects a partial discharge signal. An external noise sensor(111) detects an external noise signal. An A-D converter(120) changes the partial discharge signal and the external noise signal into a digital signal. A peak detector(140) extracts the peak value of the waveform of the digital signal according to each sensor. An arrival time detector detects the time of arrival by detecting the starting point of the partial discharge signal.
