Megger 230415 AC High-Pot Tester, 0 to 4 kV

The Megger 230415 AC High-Pot Tester is designed for safety and ease of operation, and readily adapts to development, maintenance or production testing. The 230415 Tester features a front-panel, NEMA 5-15R three-prong output receptacle.

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 230415 also features 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 lamp lights to confirm that the 230415 Tester is connected to a properly grounded power source.

The 230415 AC High-Pot Tester will automatically shut down if ground circuit resistance of the test object exceeds 15 ohms at any time during testing. This feature may be bypassed when testing double-insulated devices or when using test probes.
