GDCY-20 20kV Impulse Voltage Generator IVG
Product Description
The impulse voltage generator is mainly used to the field of impulse voltage tests by lightning impulse voltage full wave, lightning impulse voltage chipped wave and operate impulse voltage wave for such test products as electrical instrument.
Features
- Complete equipment and wide voltage levels in the whole set of device .
- Small electric inductance in the return circuit of the impulse voltage generator,A band-stop filtering is adopted so that a standard impulse wave is still generated even under a large capacity load, and large load capacity.
- Large in voltage utilization coefficient.
- Convenient in wave adjustment, simple in operation, excellent in synchronization performance and reliable in motion.
- An automatic control technique is adopted in the constant-current charge,which is high automation and strong anti-interference capacity.
- A digital measurement and analysis system for the impulse test date are adopted,which increase the technical level and the efficiency of the impulse voltage tests.
