    •
  • Power range: Below 6,800 kVA. 
The AC resonant test systems with variable inductance (WR) 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 frequency by setting the variable inductance of the HV reactor. If the HV reactor and test object are designed to form a series resonant circuit, the result will be an ideal sinusoidal testing voltage. The oil-cooled HV reactor is installed in a closed steel tank.
