Abstract

Disclosed are a system and a method of detecting a partial discharge position. The system comprises: a partial discharge sensor detecting an electromagnetic partial discharge signal; a waveform monitor measuring a waveform of a partial discharge signal detected by the partial discharge sensor; a conversion module converting the waveform and dividing the partial discharge signal according to each transmission mode; and a calculation module calculating a distance between the partial discharge sensor and the partial discharge position through an arrival time and a frequency of the divided partial discharge signal.

Description

technical field [0001] The present invention relates to a system and method for monitoring electronic devices, in particular, the system and method can detect the location of partial discharge. Background technique [0002] Detecting and removing discharge sources is difficult because their size is usually too small to find. Therefore, it is considered as one of the important solutions to estimate the partial discharge location more accurately to prevent the possible breakdown of the electronic device. [0003] A scheme for estimating a partial discharge position can be roughly classified into a scheme using attenuation of an electromagnetic discharge signal generated by discharge and a scheme using a difference in arrival time of the electromagnetic discharge signal at a partial amplification sensor. [0004] figure 1 is a diagram illustrating a method of detecting a partial discharge location according to the related art. [0005] refer to figure 1 , the electronic dev...
