| Abstract: | The free particle defection inside gas insulated switchgear(GIS)harm safe and steadyoperation of GIS equipment. By analyzing the characteristic of free particle in GIS, puts forward themethod to detect free particle defection in GIS using ultrasonic partial discharge detection technology.The application result shows that ultrasonic partial discharge detection technology can effectively findout free particle potential defection inside GIS equipment, ensure the safe operation of GIS equipment. |
