Inductance Adjustable High Voltage Resonant Test System for Generator Alternator


Features

1. As the resonant system is reactive power full compensated, the power of the equipment and power source is only less than 1/10 of measured equipment; with smaller volume and lighter weight compared with the equipment in same capacity. The device with large output capacity and small power supply capacity, low cost, easy to operate and safe.

2.Serial resonant system actually is current filter circuit, which make the tested equipment through current almost being fundamental current, the output voltage distortion (THD) is very small, better than current AC voltage withstand equipment.

3.The short circuit current after flash-over or breakdown is only less than 1/10 (1/Q) of the test current before the short-circuit, which can effectively prevent further damage to fault point after breakdown.

4.Auto blowout the arc after flash-over, which is a long and stable process to recover the serial resonant voltage, so it is very safe.
