I. Product Feature 

Huazheng Electric DC HV generator is widely applied in the DC HV tests carried out for the zinc oxide lightening arrester, magnetic blow-out arrester, power cable, generator, transformer, circuit breaker, etc.

HZZGF-Z intelligent series of DC HV generator has the following main technical characteristics and functions:

1. Use large touch LED screen with human-machine dialogue function;

2. Full-automatic MOA voltage rise measuring function: good repeatability, high accuracy;

3. Automatic voltage rising function: With preset test voltage, the output voltage can be maintained constant;

4. Automatic timing function: Preset the voltage rising time of the standard test voltage, after rising to the standard test voltage, the timing will start automatically, when the timing is completed the voltage will drop automatically;

5. The HV over-voltage setting uses micro-processor for setting, which is highly precise and highly reliable;

6. Preserve the manual test mode;

7. Data storage function: Being able to timely catch the test parameters and automatically preserve the test results;

8. Based on the electromagnetic compatibility theory, use the special shielding, multi-level isolation and grounding and various other protection strategies to form a organized protection combination, during discharging under rated voltage the equipment will not be damaged;

9. HF, ZGF totally intelligent series of DC HV tester possesses the online operation function with built-in online control software. The host computer (such as being equipped with PC) is installed with control software and auxiliary communication cable (optional) which can realize the online control.
