Measurement of the resistance of grounding elements, metal connections, continuity of protective conductors using a two-, three- or four-wire method.
Measurement of soil resistivity.
Measurement of AC voltage (noise).
Measurement of resistance of grounding elements, metal connections, continuity of protective conductors by two and three-wire method.
The test device PN-20 is designed to test and evaluate the insulation resistance of non-energized high-voltage cable lines, insulators, couplings, motors and other equipment, as well as to test high-voltage arresters with a constant voltage of 0.5 to 20 kV. The device can be used by line personnel for operational control of the insulation condition before putting the equipment into operation after installation or repair.
