ZGF-120kV5mA Automatic DC High Voltage Tester

Model: ZGF-120kV5mA  DC High Voltage Tester

Application:

This instrument is suitable for conducting DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers, and generators.

Feature:

1. The output voltage is stable, and a high-frequency voltage doubling circuit is adopted.

2. It has a complete set of protection functions and is equipped with a nanosecond-level dedicated sensor.

3. It has the 0.75U function and can automatically switch to the 0.75U state.
