FVGA-120kV/5mA Series Intelligent DC High Voltage Generator

Introduction：

FVGA-120kV/5mA Series Intelligent DC High Voltage GeneratorIt is a lightweight DC high voltage tester developed and manufactured according to industry standards. This product is suitable for conducting DC withstand voltage tests and DC leakage current tests on equipment such as zinc oxide lightning arresters, magnetic blown lightning arresters, power cables, generators, transformers, switches, etc. in power departments, power plants, industrial enterprises, research institutions, railways, chemical industries, power plants, etc.

The application of manual and automatic technology in DC high-voltage generators has greatly improved the accuracy of the instrument and the efficiency of work. 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, not current values and voltage drift. On the basis of maintaining the manual 0.75UDC1mA function button, AI fully automatic zinc oxide arrester measurement, cable segmented voltage withstand test, automatic voltage withstand test functions are added, and test reports can be directly printed and saved, avoiding the problem of handwritten errors in experimental reports (data storage can only start from 002). The manual mode is retained, and the printing function under any voltage and current, as well as the total time T1 and segmented timing T2 functions are added. The instrument has added perpetual calendar and time functions, and the experimental report includes time and date.
