Abstract: If discharge occurs during the test, the overall disassembly or segmentation pressurization is required to determine the discharge position, resulting in long maintenance time for the staff and even affecting the progress of the project. This paper designed a set of vibration discharge positioning system adopting the vibration acceleration sensor to monitor the amplitude and accumulated value of the pressure wave to determine the discharge position. The fault type was determined by the spectrum analysis of the discharge data. The 252 kV GIS equipment test platform was built to simulate three typical discharge faults. The test results confirmed that the system can quickly help the field personnel to determine the discharge position and discharge type, which can reduce the maintenance time of the equipment, reduce the workload of the personnel, and speed up the project progress.
Key words: gas insulation switchgear; vibration; discharge; positioning; fault
