PGK 25 (Rental) - BAUR DC Hi-Pot Testing Unit

Cables must be tested in compliance with the national and international standards. This applies before the commissioning of new cable networks. The portable BAUR PGK 25 cable test device is used for DC voltage testing in low- and medium-voltage cables. It is characterised by its low weight of only 16.5 kg, by the easy operation and solid construction for onsite use.
 

• Integrated timer of 1-30 min (± 1 min) with automatic limit switching and triggering of the discharge unit
• Continuously adjustable output voltage 0 - 5 kV and 0 - 25 kV DC
• The voltage measurement is done directly at the high voltage output
• Switch-on interlock of high voltage against unintended commissioning

Core Use Cases

• Insulation testing of:

  • Paper‑insulated, mass‑impregnated (PILC) power cables

  • Transformer and motor windings

  • High‑voltage insulators

• DC high‑voltage testing of medium‑voltage network equipment up to 25 kV, especially in field conditions

• Cable sheath testing according to IEC and IEEE standards

What the PGK25 Actually Does

• Applies 0–5 kV or 0–25 kV negative‑polarity DC voltage

• Measures leakage current (1 μA to 10 mA ranges) to assess insulation health

• Performs timed tests (1–30 minutes) with automatic discharge for safety

• Can operate from AC mains, internal 12 V battery, or external 12 V supply

Typical Field Applications

• Commissioning tests on newly installed cables

• Periodic maintenance tests on aging cables

• Fault localization workflows (as part of a broader test suite)

• Quick on‑site verification of insulation before energizing equipment

Why It’s Used

The PGK25 is valued because it is:

• Portable (≈16.5 kg)

• Rugged for field use

• Simple to operate with clear controls

• Compliant with major standards (IEEE 400‑2012, IEC 60060‑3, IEC 60229, etc.)
