Customization XHZG Series 60kV 120kV 200kV 300kV DC Hipot Tester DC High Voltage Generator
Scope of applicationThe DC high-voltage tester is mainly applicable to the DC withstand voltage test or DC leakage current test of zinc oxide arrester, power cable, transformer, circuit breaker, generator and other high-voltage electrical equipment by the power department of electric power department, industry and mining, metallurgy, iron and steel and other enterprises.
Boost mode: manual boost
XHZG series DC hipot tester Using aipwm technology, the inaccurate linearity of PWM technology is adjusted, and the accuracy of the instrument is greatly improved. The AI technology screen is used to set overvoltage protection and overcurrent protection, which replaces the problem that the digital dial switch can only set the voltage value, but can not set the current value and voltage drift. 0.75udc1ma function button, convenient for zinc oxide arrester test, accuracy ≤ 0.5%. The timing function under any voltage and current, total time T1 and sectional timing T2 are added. The instrument adds the functions of perpetual calendar and time.
·The case adopts portable case, which is easy to carry.
·Using aipwm technology, the inaccurate linearity of PWM is adjusted, and the accuracy is greatly improved. Ripple coefficient ≤ 1%.
