Description
The ALT series of AC Dielectric Test Sets provide continuously adjustable AC output voltages used to provide a go/no-go, or pass/fail AC voltage withstand test on high voltage apparatus, like switchgear, circuit breakers, reclosers, vacuum bottles, hot sticks, rubber products, motor windings, bus duct, insulators, and any other apparatus needing an AC voltage insulation proof test. The Alt Series offer the most portable, affordable, and easiest to use AC testers at this voltage and power.
