Application range
The DC high voltage tester is mainly suitable for the power department of the power department, industrial and mining, metallurgy, steel and other enterprises to conduct DC withstand voltage tests or DC leakage current tests on zinc oxide arresters, power cables, transformers, circuit breakers, generators and other high-voltage electrical equipment.
Boost mode: manual boost.
Technical features
ZGF-B DC high voltage generator. Using AIPWM technology, the inaccurate linearity of PWM technology has been adjusted, so that the accuracy of the instrument has been greatly improved. And the use of AI technology to set overvoltage protection and overcurrent protection on the screen replaces the problems that the digital dial switch can only set the voltage value, but cannot set the current value and voltage drift. 0.75UDC1mA function button, convenient for zinc oxide arrester test, accuracy ≤ 1%. Added the timing function under arbitrary voltage and current, and the functions of total time T1 and segment timing T2. The instrument has added perpetual calendar and time functions.
·The chassis adopts a portable chassis, which is easy to carry.
·Using AIPWM technology, the inaccurate linearity of PWM has been adjusted, and the precision has been greatly improved. Ripple factor ≤0.5%.
· AI zinc oxide arrester and oil-immersed transformer measurement function. The experimental report can be saved directly, with an accuracy of ≤0.5%. Keep manual 0.75UDC1mA.
·The use of AI technology to set overvoltage protection and overcurrent protection replaces the problem that the digital dial switch can only set the voltage value, but cannot set the current value and voltage drift. Error≤1%
Full-scale smooth voltage regulation, voltage regulation accuracy ≤ 1%, stability ≤ 1%, voltage and current error ≤ 1.0% ± 1 digit
·With total time T1 and split timing T2, and timing function under any voltage and current.
·The perpetual calendar and time functions are added to the instrument.
