| Abstract |
The disastrous accident happens and the economic loss comes into being at the power facilities that used a industry site, if the fault comes into being. This paper experiments the partial discharge in the GIS used a SF? insulation gas by the pressure change. We studied the influence of particles at the partial discharge in a SF? gas. We use UHF method and measure the partial discharge signal radiation electromagnetic waves and to be happened at the SF?. And we analyzed the influence on the SF? gas to have the particles which the partial discharge analyzes a spectrum of the radiated electromagnetic waves and comes out. The paper results aided the prevention of breakdown accident that happened by particles when an inside pressure changes at the GIS & the power facilities used SF? gas. |
