1、 Application scope

This series of intelligent DC high-voltage generators is mainly suitable for power departments, industrial and mining, metallurgy, steel and other enterprises to conduct DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide lightning arresters, power cables, transformers, circuit breakers, generators, etc.

By using AIPWM technology, the inaccurate linearity of PWM technology has been adjusted, resulting in a significant improvement in instrument accuracy. And AI technology is used to set overvoltage protection and overcurrent protection, replacing the problem of digital dial switches only being able to set voltage values, unable to set current values and voltage drift. AI fully automatic zinc oxide arrester measurement and automatic withstand voltage test functions are added, and test reports can be directly printed and saved. Manual mode is retained, and printing function at any voltage and current, as well as timing function, are added. The instrument has added perpetual calendar and time functions, and the experimental report includes time and date.
