Baur PGK25 DC HV Tester

The portable Baur PGK 25 DC HV tester is designed for DC voltage testing up to 25 kV of paper-insulated mass-impregnated cables and electrical equipment in medium-voltage networks.

The PGK 25 is characterised by its low weight of only 16.5 kg, easy operation, and solid construction for on-site use. The device can be operated via the mains, an integrated rechargeable battery, or an external power supply, making it suitable for universal use.

An external curve tracer can be connected to record the measured current in relation to time. The timer permits test time pre-selections of 1 to 30 minutes. After the test completes, the integrated discharge unit—designed for a maximum discharge energy of 5000J—is automatically activated.
