The ALT 300(F) was primarily designed for testing bucket truck booms and liners per the ANSI 92.2 standard. However, its continuously adjustable dual output voltages, high power rating, and mobility also make it ideal for field testing other high capacitance loads requiring AC withstand testing. This unit is also used for overvoltage AC withstand testing of ISO phase bus, switchgear, circuit breakers, reclosers, vacuum bottles, and hot sticks.
