HV DC Hipot Tester is a high voltage direct current (HV DC) testing device used to verify the electrical insulation of cables, wires, transformers, and other electrical equipment. It applies a high voltage to the equipment and measures the leakage current to ensure that the insulation is able to withstand the specified voltage without breakdown.

1. High accuracy and correct measuring.Voltage and current meter all have digital display,with voltage resolution 0.1kV,and current 0.1uA.Voltage value applied to load test object is displayed directly through voltmeter on control cabinet,which needn’t to be connected with voltage divider on the outside when using,and lead connection is eas
2. High stability in voltage regulation,smooth voltage regulation in full range.Voltage regulation of output adopts import single multi-rings potentiometer with rough adjustment and fine adjustment.Accuracy of voltage adjusting is better 0.1%,accuracy of voltage and current measuring is less than 1.0%,and ripple factor is better than 0.5%.
3. Negative polarity output,zero start,continuous adjustable,having the function of over voltage,over current,zero returning and ground protection.Operation is safe due to strong function of auto protecting circuit,technical index of all kinds surpassing industry standard and similar products.

High voltage DC generator provides the most dependable,portable DC high voltage sources for checking the quality of zinco xide arrester,magnetic blow-out arrester,power cable,generator,transformer,and switchgear.It is widely applied in electric power department,scientific research unit,railway station,power plant,chemical plant,etc.For the DC hipot tester,it has two functions:For the DC high voltage test and DC leakage current test.
