The High Voltage PFT-503CM Portable AC Hipot Tester is ideal for a variety of Field and General Repair Shop HV testing applications
The PFT Series operates from a standard 120V source and incorporates capacitve compensation which allows a 3kVA test load to be tested with only 1kVA of input power.
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. A gapped core transformer for up to 3 kVA of output power with the draw of only 1.5 kVA so the hipot can be powered by a standard 120Vac or 230Vac input. 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.
