Research on Flashover Localization in GIS Based on Acoustic Pressure Characteristics
This paper introduces a kind of methodSon GIS flashover discharge location based on it’s Acoustic Pessure Characteristics. This method uses piezoelectric sensors to gain acoustic pressure signal, and then use sound pressure Detection technology and signal processing technology to set research model. Through the comparison of acoustic pressure signal, flashover discharge point will be found. Digital simulation shows that the acoustic pressure signal brought by flashover discharge is concentrated in the audio range of partial discharge. By measuring the difference between acoustic pressure signal from different part, fault point would be found. The result of this article can be used for research and manufacture of flashover discharge localization sensor and equipment.
