PGK 25 DC high-voltage test device

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.

Manufacturer: BAUR (Austria).

Description

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.
Features
  • Two continuously adjustable voltage ranges: 5 kV / 25 kV
  • Integrated timer for setting the test time
  • Ammeter with 5 measurement ranges from 1 μA to 10 mA
  • Connection for external curve tracer for recording the test current
  • Voltage measurement directly at the HV output
  • Automatic switch off at the end of the test and triggering of the discharge unit for maximum safety
  • Switch-on interlock of high voltage against unintended operation
