AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

The resonant test systems can be either in insulation cylinder type or metal tank. Insulation cylinder reactors are in module and can be stacked to connect in series parallel to get much higher voltage or current. Additional voltage taps are possible for metal tank reactors. The output voltage is fed out through the tap-changers by HV bushings. This kind of reactors extend application range, and satisfy testing for cables of various voltage class.
