Vlf High Voltage Tester

VLF HV testers are the new generation of AC hipot testers but with an output frequency of 0.1 Hz or lower rather than 50/60Hz. Although the frequency is very low, it is still an alternating current with polarity reversals every half cycle. At 0.1 Hz output, rather than 50Hz, it takes 500 times less current and power to apply an AC voltage to a capacitive load, like a long cable. There is no better way to verify the AC integrity of a cable than to hipot it with AC voltage.
Now very Low Frequency (VLF) testing is internationally accepted as a safe and effective method for testing high voltage facilities. Not only for cable testing, but also spreading rapidly to others where similar benefits are evident, such as transformers, generators and etc.
VLF HV tester are used to provide a go/no-go, or pass/fail, AC voltage withstand test. It can also be used as the voltage source for diagnostic cable testing.
FSVLF series VLF HV testers are microprocessor controlled, have automatic functions for stepping-up, stepping-down, measuring and protecting. They are portable, light weight and small volume. Output waveform is clearly displayed on the large LCD and test report can be printed by built-in thermal printer.
FSVLF-80 VLF AC Hipot Tester High Voltage Generator for 35kV cable HV Test , mainly used for voltage test of 35kV cables and generators.
