Portable AC Hipot for Apparatus Testing

The PFT Series of portable AC hipot test sets are ideal for a variety of field and repair shop testing applications. These inexpensive, compact and light weight units are rugged and reliable. Our 3 kVA models feature capacitive load compensation enabling full load testing with a power draw of 1.5 kVA while operating from a conventional line input.* Models below 100 kVac are single piece units with a shielded cable output for fast and easy test setup. The PFT-103CM, PFT-303CM, PFT-503CM, and PFT-1003CM are compensated enabling testing of 3 kVA loads with a power draw of 1.5 kVA and operate from a conventional electrical source*. In addition, these units include a dual range kilovolt meter, triple range output current meter and a guard/ground return mode enabling the operator to measure the total current to ground or only the current flowing through the sample under test.

The PFT-103CM(F) AC hipot test set provides continuously adjustable output voltages for overvoltage withstand testing of the following:

• Switchgear
• Circuit breakers
• Reclosers
• Vacuum bottles
• Hot sticks
• Motor windings
• Other high voltage insulation requiring AC
