Used for higher energy applications, AC and AC/DC High-Pot Testers available from Megger are designed for safety and ease of operation, and readily adapt to development, maintenance or production testing. This is the 0-3kVAC model.
Test voltage is continuously adjustable from zero to full output, with a zero-start interlock. Leakage current trip level may be adjusted from 0.3 to 12 mA by a front-panel knob. Pushbuttons are provided to select one-second or continuous testing, to turn off the high voltage and to reset the instrument. All high-voltage connections are recessed to prevent accidental contact with high voltage.
During testing, high voltage will automatically shut down within 50 ms of arcing or exceeding the preset trip level. Visual and audible alarms alert the operator upon failure.
The instruments also feature an interlock that prevents the high voltage from being applied if the supply ground wire is open or if the hot and neutral wires are interchanged. A Tester Grounded lamp lights to confirm the instrument is connected to a properly grounded power source.
This unit has not been tested, and does not include any test leads.
