PGK 50 E / PGK 80 E DC HV tester

The portable PGK 50 E and PGK 80 E DC HV testers are used for DC voltage testing up to 50 kV or 80 kV of paper-insulated mass-impregnated cables and electrical equipment in the medium-voltage network.
Sensitive current measurement permits the detection of extremely small insulation currents, which are used to determine insulation resistances up to the tera-ohm range. An external curve tracer can be connected to the PGK 50 E/PGK 80 E to record the measured current in relation to time.
The integrated discharge unit operates automatically and independently of the device situation, even in the event of power failure. A clear switching noise can be heard. The discharging resistance is designed for a max. discharge energy of 8 000 J. Thanks to their small dimensions and the practical case with carrying handle and carrying strap, the PGK 50 E and PGK 80 E are optimal for use on site.
