AC Resonant Test System

AC resonant test system with variable inductance and metal tank type is 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.

Additional Product Information

Features & Benefits

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.
Low power demand due to high quality factor;

  1. Low level of partial discharge < 5 pC;
  2. Higher duty cycle thanks to excellent cooling properties;
  3. Ideal sinusoidal test voltage for series resonance systems;
  4. Low noise level thanks to special mechanical design;
  5. Low maintenance operation over the entire service life
  1. For routine testing of medium and high voltage cables up to 400 kV according to IEC 60502 and IEC 60840
  2. For routine testing of high voltage capacitors up to 60 kV according to IEC 60871
  3. For routine and inspection testing of generators and motors up to 60 kV according to IEC 60034
