Using resonance between capacitive test object and inductive HV reactor of the test system to generate a continuous sinusoidal high voltage in 50/60Hz, resonant system is lighter and more economic than AC test transformer systems because only the loss in test circuit must be covered by power supply.

Power frequency HVAC resonant test systems are designed to compensate capacitance in testing circuit precisely by adjusting inductance of HV reactors, and output continuous AC voltage of power frequency (50/60Hz), mainly for AC withstand voltage and PD testing of high and ultra-high voltage cables, power transformers, GIS, generators, motors, etc.

 

They use resonance between capacitive test object and inductive HV reactor of test system, adjust inductance of HV reactor to form a series resonant circuit with test load, resulting in an ideal sinusoidal resonance voltage. The natural resonance frequency of test circuit is matched to feed-in mains frequency 50/60 Hz by tuning inductance of HV reactor.

 

As part of a series resonant circuit, these systems provide undistorted high 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.
