HV Lightning Impulse Voltage Generator AC Hipot Test System 300kV/20kJ
Product Description:
HZCJ-4800kV/20kJ impulse voltage generator is used for impulse voltage test of
lightning impulse voltage full wave , lightning impulse voltage chopped wave and operation impulse voltage wave which apply to electrical equipment ect. Multiple waveform impulse voltage generator can produce eight
kinds of waveforms of standard lightning wave, operation wave, lightning chopped wave, oscillating lightning wave, oscillating operation wave, line insulator steep wave, composite insulator steep wave,
transformer induction operation wave. The technology index accords with national standard and IEC standard, is in the leading
position at home and has reached an advanced level in the world.
Product Features:
1. Use constant current charging technology, high automation, strong anti-interference performance.
2. Use digital measurement and analysis system and computer on line processing system for impulse test data, greatly improve the test technology and efficiency.
3. Complete sets, full voltage classes.
4. Simple operation, excellent synchronization performance, reliable action.
5. Small loop inductance, take the band elimination filter measures, still produce standard impulse wave in the large-capacity load , large load capacity, high voltage utilization, convenient to adjust wave.
