Portable 120kV High Voltage VLF Hipot Instruments , Universal VLF & DC HV Test System
120kV DC Hipot Tester
Model: HZF-120/5
DC Hipot Tester is used for DC voltage withstand test and leakage current test of HV electrical equipment. The separate units make the operator keep enough safe distance with high voltage circuit.
DC Hipot Tester HZF-120/5 can output 120kV voltage and 5mA current.
Main Features
1)High precision and accurate measurement.
2)Voltage regulation stable, full-scale smooth voltage regulated, the output voltage adjustment using imported single multi-turn potentiometer, step-up process smooth, high precision adjustment.
3)Negative polarity output, zero start, continuously adjustable, over-voltage, over-current, return to zero, ground protection, special disconnection protection and other protection functions.
4)Increase the high precision 0.75UDC1mA function, brings great convenience to do zinc oxide arrester measurement.
5)Overvoltage setting using a digital DIP switch can set the voltage value of the visual display in units of kV.
