1、 Application scope

Intelligent DC high-voltage generators are 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.

Intelligent DC high-voltage generator. By applying 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 that digital dial switches can only set voltage values, cannot set 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 Retained manual mode, added printing function under arbitrary voltage and current, as well as total time T1 and segmented timing T2 functions. The instrument has added perpetual calendar and time functions, and the experimental report includes time and date.

Note: When connecting a wireless transmission microampere meter, the host needs to be set to wireless microampere meter mode! When wireless mode is not required, simply set the host to internal microampere meter mode! (Optional wireless microampere meter)
