ZGF-II series DC high voltage generator is a special equipment for power departments and industrial and mining enterprises to perform DC withstand voltage test and leakage current test on lightning arrester, cable and high voltage equipment.
The ZGF II series DC high‑voltage generator is a compact, lightweight device used by power utilities and industrial plants for DC withstand and leakage‑current testing of surge arresters, cables and high‑voltage equipment. It incorporates modern power‑electronics, PWM modulation, and MOSFET technology to deliver high output power with low ripple, and includes multiple protection functions such as over‑voltage, over‑current and zero‑position lock.
The manual provides safety guidelines, detailed wiring and grounding instructions, step‑by‑step operating procedures, adjustment of voltage and current settings, and troubleshooting tips. It also lists the accessories supplied with the unit and the technical specifications for various model variants. This manual is written in Chinese.
| Input voltage | AC 220 V ±10 %, 50 Hz ±1 % |
|---|---|
| Output voltage indication accuracy | < 1 class |
| Output current indication accuracy | < 1 class |
| Ripple factor | ≤ 0.5 % |
| Operating temperature range | -10 °C to 40 °C |
