PGK 25 DC HV tester

The portable PGK 25 DC HV tester is used for DC voltage testing up to 25 kV of
paper-insulated mass-impregnated cables and electrical equipment in the medium-
voltage network.
The PGK 25 is characterised by its low weight of only 16.5 kg, by its easy operation and by its solid construction for onsite use. The device can be operated via the mains, an integrated rechargeable battery or an external power supply and is therefore suitable for universal use.
An external curve tracer can be connected to the PGK 25 to record the measured current in relation to time. The timer permits test time pre-selections of 1 to 30 minutes. After the end of the test time, the integrated discharge unit is automatically switched off. The discharging resistance is designed for a max. discharge energy of 5 000 J.
