ALT-300(F)
AC voltage testers
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.
Features:
- Secondary connected 2 Range Voltmeter: 120/300kV
- 2 Range Current Meter: 0-250uA and 0-1.0mA with x1, x10, x100 multipliers up to 100 mA
- 19 inch rack benchtop style control
- Fixed overload set to 120% of variable transformer rated output current
- Transit protected meters prevent meter damage between test sites
- Guard/Ground circuit for accurate leakage current measurement
- Zero Start and External safety Interlock provisions
