The Intelligent DC high-voltage generator series is primarily suitable for power departments, industrial and mining enterprises, metallurgical industries, steel enterprises, and other corporate power departments to conduct DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers, generators, and so on.
Using AIPWM technology, the inaccurate linearity of PWM technology has been adjusted, significantly improving the accuracy of the instrument. AI technology is adopted to set overvoltage protection and overcurrent protection, replacing the digital dial switch that can only set voltage values but not current values and has issues with voltage drift. It adds AI-based fully automatic zinc oxide arrester measurement and automatic voltage withstand test functions, and can directly print and save test reports, while retaining the manual mode.
