AC Resonant Test System

1.Suitable for the partial discharge and induction withstand voltage test of power transformer of 400kV/350MVA and below;
2.AC power frequency converter adopts a linear amplification circuit; sine wave output with small waveform distortion.
3.Automatic and steady voltage adjustment.
4.Overvoltage, overcurrent and other protection functions make the device safe and reliable.

1. The required power supply capacity is greatly reduced to 1/Q (usually Q≥10) of the traditional power capacity.
2. Smaller in size and lighter in weight with the same capacity.
3. The waveform distortion rate is less than 1%.
4. The applied series resonance is characterized by a steady voltage boost and easy operation.

1.The required power capacity is greatly reduced, which is only 1/Q of the test capacity.
2. The weight and size of the device is greatly reduced to 1/10-1/30 of the taditional test device.
3. Obtaining a good sinusoidal waveform by reducing the waveform distortion of output voltage.
4. Efficiently finding the insulation weakness and preventing large short-circuit current from burning the fault point.

1. The required power capacity is greatly reduced
2. The weight and volume of the device is greatly reduced.
3. There will be no recovery overvoltage.
4. The device has over-voltage, over-current, zero start, system detuning (flashover) and other protection functions.
