To ensure the frequency meeting the requirements of power frequency caused by the large capacity of GIS equipment, the equipment was divided into two sections to carry out the experiment. The test included sophisticated test, AC voltage test and partial discharge test. The maximum test voltage was 1100 kV. The test was completed on the first try with zero defects, which could provide technical support for the following AC voltage test in the UHV substations.
