Testing Items: Withstand Voltage Testing(i.e Insulation Level Testing), Current Leakage Testing
DC high voltage generator is mainly used in the electric power department, power department of industrial and mining, metallurgy, iron and steel enterprise for zinc oxide lightning arrester, power cables, transformers, circuit breakers, generators and other high voltage electrical equipment of DC withstand voltage test or DC leakage current test. ZGF type DC high voltage generator used AIPWM technique, adjusted the inaccuracy linearity of PWM technology, let the instrument precision greatly improved.
Product Details:
Product Introduction and Features:
1. Stable output voltage: Adopts high frequency multiple-voltage circuit, the lastest PWM pulse width modulating technology and voltage current double-closed loop feedback technology, which improves the adjusting rate of power and non-load, ensuring stable voltage.
2. High voltage resolution: The host voltage meter directly displays the voltage value on the non-load end, no need to connect extra voltage divider. The voltage resolution gets to 0.1kV, current resolution gets to 1uA.
3. Special 0.75 function: Add intelligent high-precise 0.75U functional button, especially for the metal oxide zinc arrester testing.
4. 0V position voltage rising: The booster rises from 0V, utilizing imported multiple-circle potentiometer. The voltage rising process is stable, high adjustable accuracy.
5. Over-voltage Setting: The over voltage setting selects digital dialing switch, easy to operate, and having high setting accuracy.
6. Reliable performance: The critical components are imported. Multiple-voltage cyclinder uses special insulated coating, no leakage.
7. Complete protection: Having protective functions of 0V position, over-voltage, over-current, breakdown. The protective circuit adopts nano second transducer, acting rapidly and reliably, effectively ensure the safety of workers and equipment.
8. Integrated designing: Adopts integrated designing, the host and multiple-voltage cylinder can be put in one case.
