Working Principle

Before using the high-voltage pulse generator, select the appropriate function switch and voltage range switch, then press the start button to increase the high voltage. The test cable will then be tested following the procedure shown in the diagram. After use, the internal system will automatically discharge the remaining high voltage from the energy storage device, and this will be indicated on the voltmeter. The workflow diagram is as follows:

Side panel description

1. Power Socket (220V 50Hz): Power supply for the instrument, AC220V connection port;

2. Fuse Holder: Fuse holder for the AC220V power supply system;

3. Signal Connector: Uses a dual-Q cable to connect the instrument to the cable fault tester for flashover waveform acquisition. Only effective during high-voltage flashover.
