Variable Inductance Ac Resonant Test Systems

We manufacture, export and supply Variable Inductance AC Resonant Test Systems in Yangzhou, Jiangsu, China. AC resonant test systems with variable inductance and metal tank type are used for factory testing of medium and high voltage cables, high voltage capacitors, generators, and motors. They use the resonance between the capacitive test object and the inductive HV reactor of the test system to generate a continuous sinusoidal high voltage.

The oil-cooled HV reactor is installed in a closed steel tank. The high voltage is fed outward through the steel tank through a HV bushing. The reactor can be fitted with additional voltage taps (bushings) to achieve largest testable capacitances of test objects at lower test voltages.

Applications;
For routine testing of medium and high voltage cables up to 400 kV according to IEC 60502 and IEC 60840
For routine testing of high voltage capacitors up to 60 kV according to IEC 60871
For routine and inspection testing of generators and motors up to 60 kV according to IEC 60034
