DHVT Series 60 TO 400KV DC High Voltage Generator Anti-interference Dc High Pot

Description:

DHVT Series DC high voltage generator, suitable for electric power companies and enterprise power department to conduct DC withstand voltage test and DC leakage current test on zinc oxide arresters, power cables, generators, transformers, circuit breakers, etc. which is a necessary test instrument for high voltage tests.

Five innovative technologies:

1. Super high voltage stability, and voltage closed loop large feedback is adopted

2. Ultra-safety, with reliable fast protection circuit, no damage when high voltage is continuously discharged to ground

3. Ultra-lightweight, adopt intermediate frequency voltage double 35-50kHz inverter frequency and PWM pulse width modulation, with small ripple factor

4. Good electrical performance, using latest PWM pulse width modulation technology and high-power IGBT devices

5. Strong anti-interference performance, stable and reliable, fully shielded chassis and main components
