DC Hipot Test Set Transfoer DC High Voltage Withstand Test Eqipment 500KV/5mA
GDZG-300 series of DC Hipot test set is testing DC high voltage for zinc oxide lighting arrester, magnetic blowing arrester,powercables,generators,transformers, switchesand otherequipment, which is suitable for electric power branch,power department of factories,scientific research units,railway,chemicalindustry, power plants.
Features
1. Simple operation and complete function,easy for wild work.
2. Higher voltage stability,smaller ripple coefficient.
3. More reliable and stable,continuous short-circuit discharge directly to ground.
4. Intelligent grounding protection and alarm function. High precision, accurate measurement, LCD screen displays voltage and current.
5. High stability of voltage regulation, smooth voltage boosting process,high adjustable precision,with coarse and fine adjust ment functions.With over-voltage setting,timing and protection indication.
6. With function of high-accuracy 75% VDC-1mA,more convenient for zinc oxide lighting arrester DC testing.
7. HV booster is small size and large capacity,with-Y shoring in the packing,which is portable to carry.
