300kv / 20kj Impulse Voltage Test System High Voltage Insulation Tester
Product Description:
HZCJ-DY series 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. Complete sets, full voltage classes.
2. 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.
3. Simple operation, excellent synchronization performance, reliable action.
4. Use constant current charging technology, high automation, strong anti-interference performance.
5. Use digital measurement and analysis system and computer on line processing system for impulse test data, greatly improve the test technology and efficiency.
