It is a portable DC voltage tester.
It is used in dielectric testing on both wires and cable installations.
The RPA insulation tester is a DC voltage to measure insulation resistance in both wires and cable installations in compliance with VDE standards.
The RPA 80C (80 kV) and RPA 120C (120kV) include an operating unit and a high voltage unit in two separate modules.
Its compact, lightweight design allows easy transport to trial sites.
It has totally digital measurement, it measures: voltage, current and resistance. Auto-range in current, maximum output voltage limit.
