Features and Benefits

0 – 30 kV AC Power Frequency AC Hipot

The PFT-301CM and PFT-301CMF are from our popular PFT Series of field portable AC hipot test sets. These hipots provide continuously adjustable AC voltage used for a pass/fail, AC over-voltage withstand test on high voltage apparatus, like switchgear, circuit breakers, reclosers, vacuum bottles, hot sticks, bus duct, and any other apparatus needing an AC test voltage. The PFT Series offers the most field portable, affordable, and easiest to operate AC hipots at this voltage and power. Equipped with a two-range voltmeter, three-range current meter and guard circuit for precise leakage current measurements. For bench-top requirements see the ABT Series. Testing loads that require higher power, see our ALT, FPA, HPA and PAR lines of AC dielectric test sets.
