• 1. Due to full compensation of resonant reactive power, the power of the power supply and equipment is only less than 1/10 of the required capacity of the test sample (1/Q>10); The device has a small volume, light weight, large output capacity, and requires a small power supply capacity. It is inexpensive, easy to operate, and safe to use;

• 2. Series resonance is actually a current filtering circuit, which makes the current passing through the test sample basically the fundamental current, and the waveform distortion rate (THD) of the output voltage is extremely small, which is superior to all types of existing AC withstand voltage equipment;

• 3. The short-circuit current after flashover or breakdown of the test sample is only 1/10 or less of the pre short-circuit test current (1/Q), which can effectively prevent the expansion of damage to the fault point after breakdown;

• 4. Immediately after flashover, the arc will be automatically extinguished, and the process of establishing the resonant state voltage after extinguishing the arc is relatively long (in seconds), which is a steady-state establishment process without considering voltage overshoot or the danger of restoring overvoltage in microsecond level and millisecond level transient processes.
