HZZGF Portable Cable DC Hipot Test Equipment 5mA 400kV

 

Product Introduction

DC Hipot Tester is widely used in DC high voltage test of zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, circuit breakers and other electrical products.

Main technical features and functions of HZZGF series intelligent DC Hipot Tester:

1. Large-screen LCD with man-machine dialogue function;

2. Fully automatic MOA voltage boosting measurement function: good repeatability and high precision;

3. Automatic voltage boosting function: preset test voltage, output voltage can be maintained at constant voltage;

4. Automatic timing function: pre-set the test standard voltage compression time, automatic timing after boosting to the test standard voltage, automatic reducing voltage after the time completion;

5. Over-voltage setting is analyzed by microprocessor , high precision, good reliability;

6. Kept the manual test mode;

7. Data storage function: it can instantly capture test parameters and automatically save test results;

8. Equipped with optical fiber microammeter, which can directly read the high-voltage side current of the test product on the control unit;

9. According to electromagnetic compatibility theory, special shielding, multi-stage isolation and grounding protection measures are adopted to organically combine, and the equipment will not be damaged when it is discharging under rated voltage;

10. HZZGF series intelligent DC Hipot Tester has on-line operation function and built-in on-line control software. The computer (such as equipped PC) can realize online control by installing control software and supporting communication cable (optional).
