I. Product Introduction & Features:
DC high voltage generator is mainly used in the electric power department, power department of industrial and mining, metallurgy, iron and steel enterprise for zinc oxide lightning arrester, power cables, transformers, circuit breakers, generators and other high voltage electrical equipment of DC withstand voltage test or DC leakage current test.Â
1. the case is portable and convenient to carry.
2. Using AIPWM technology, adjusts the PWM inaccuracy linearity make the accuracy is greatly improved. The ripple coefficient is less than 1%.
3. AI zinc oxide arrester and oil immersed transformer measuring function can directly save experiment report, and the accuracy is less than 1%. Keep manual 0.75 UDC1mA.
4. Used the AI technology screen setting over-voltage protection and over-current protection to replace the digital dial switch only can set voltage value, cannot set current value and voltage drift problem. Error of 1% or less.
5. The full measuring range smoothly adjust pressure, voltage regulation accuracy is less than 1%, stability is less than 1%, the voltage current error is less than 0.5%±1 letter.
6. with total time T1 and segmented time T2, and any voltage, current chronograph function.
7. The instrument added the calendar and time function.
