Abstract: AC voltage withstand test is the most direct and effective method to judge the Insulation Performance of Electrical
Equipments. In this paper, an AC voltage withstand test of ultra high voltage (UHV for short) shunt reactors at 1 000 kV AC
Nanyang switch-gear station was conducted. The test frequency could be limited within 45 ~65 Hz by adopting serial
resonance method and pensating capacitors and reactors. This test needs less test devices and lower
power supply capacity, thus to be suitable for field AC voltage withstand test of UHV Shunt Reactors.
Key words: ultra high voltage; shunt reactors; AC voltage withstand test
