XHHV512-12L High Voltage Surge Generator with 0～864 J Discharge Energy for Cable Testing

XHHV512-12L

For impulse discharge in cable fault testing (≤12kV) and DC withstand voltage tests of other electrical devices.

Product Features:

Automatic overcurrent, overvoltage, and overheat protection;

DC withstand voltage and impulse discharge functions;

Uniform and controllable high-voltage pulse output; 

Strong short-circuit protection, allowing direct short-circuit operation to ground;

Dual 1.5-level pointer meter display for current and voltage, providing clear and intuitive readings, making it easy to see whether a fault point has fully discharged and providing real-time feedback on the discharge process;

Accurate real-time voltage measurement on the high-voltage side;

Zero-position start protection for enhanced safety and reliability; 

Unique high-voltage measurement design, allowing the voltmeter to indicate the capacitor voltage value in real-time even when stopped, providing operators with complete control over the high voltage;

Discharge time can be arbitrarily set within appropriate intervals.

Cable Fault Detection Site

1. Check the wiring. Connect the high-voltage output line plug to the instrument's EMP terminal, and the other end to the test object. Ensure good contact between the ground wire and the high-voltage output line.

2. Pay special attention to ensuring good contact between the ground wire and the high-voltage output line. Once everything is ready, connect the AC 220V power supply.

3. After connecting the power cord, turn on the AC 220V power switch in position I. The switch indicator light will illuminate.

4. Adjust the time setting. The left half of the time setting is for the ball's engagement time, and the right half is for the disengagement time, as shown in the diagram below. This means that the two balls collide and discharge once every 6 seconds, with each contact lasting 0.05 seconds.
