Datasheet
Since the introduction of the High Voltage, Inc. line of portable and affordable VLF hipots, there is a practical method of AC field testing highly capacitive loads, particularly cables and rotating machinery. High Voltage, Inc. offers a full line of VLF AC Hipots from 30 kVac to 200 kVac with models that can test up to 50 mF of load, cables over 50 miles in length and the largest of generators or motors. Use VLF for AC Withstand stress tests and/or as a voltage source for Tan Delta and Partial Discharge Diagnostic Testing. HVI offers both its original, patented long proven oil filled power supply models with analog controls and its all new solid state, computer-micro controlled wireless design. Both have diagnostic accessories available.
