The PFT-503CM and PFT-503CMF 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.
PFT Series AC hipots test medium and high voltage electrical apparatus: vacuum bottles, hot sticks, motors & generators, rubber gloves, iso-phase bus, switchgear, and other loads requiring AC withstand testing. HVI’s AC hipots are among the smallest, lightest, and most economical available while delivering higher power ratings and enhanced features. For example, the PFT-503CM is the only single piece, 50 kV AC @ 3 kVA, shielded cable output hipot on the market. One of our most popular products, it is used worldwide for substation testing and other applications.
Standard models are available from 10 kV AC – 100 kV AC with ratings from 1 kVA – 3 kVA. Some are designed with input capacitive current compensation to minimize the input power required. All have extra durable meters, guard/ground circuit with isolated return, and a three range current meter. Two-piece models are CE marked. All of these instruments are designed to withstand the rigors of field use.
