The PFT-401CEF is a CE Marked AC Dielectric Test Set, one of many in the PFT Series of field portable AC hipot test sets. These hipots provide continuously adjustable AC voltage typically used to provide a go/no-go, or 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 equipment needing an AC voltage proof test.
