For routine HV AC testing of medium and high voltage cables up to 500 kV in accordance with IEC 60502 and IEC 60840.

Metal tank type variable inductance HVAC resonant test systems are mainly used for factory testing (AC voltage and PD measurement) of medium and high voltage XLPE cables up to 500kV rating, adopt metal tank type reactors with variable inductance, which are specially designed for big capacitance load and long time duration.

 

The oil-cooled HV reactor is installed in a closed steel tank. The high voltage is fed outward through the steel tank via 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.

 

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 natural resonance frequency of the test circuit is matched to the feed-in mains frequency 50/60 Hz by setting the variable inductance of the HV reactor.

 

As the HV reactor and test object are designed to form a series resonant circuit, the result will be an ideal sinusoidal testing voltage. And because the systems are designed to have high quality factor (Q), low input power is required (1/Q) which results in lower installation and operating costs.
