Impulse Voltage Test System – High Voltage Test Instruments
● 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.
