Partial discharge testing

Applications: Partial discharge testing | BAUR GmbH

Partial discharges occur at faults in the cable, e.g. at electrical trees, joints and terminations. Partial discharge diagnostics is used to determine possible fault locations in cables and accessories before they lead to failure. This makes it possible to rectify the problem in a timely manner and prevent any subsequent damage resulting from uncontrolled failures. Partial discharge measurement is effected in accordance with standard IEC 60270.

Partial discharge measurement can detect the following:


  • Faults in new and old cable accessories, such as incorrectly fitted joints 
  • Faults in the insulation of XLPE cables (e.g. electrical trees)
  • Insufficient mass-impregnated paper insulation due to drying
  • Mechanical damage to the cable sheath

BAUR PD measuring devices can diagnose the following:


  •  PD localisation
  •  PD level
  •  PD inception voltage / extinction voltage
  •  PD frequency

  • Phase-resolved PD presentation for every 
  • Fault
  • PD interference filter function
  • Joint localisation
Applications: Combined presentation of location and PD assessment | BAUR GmbH

Phase-resolved PD presentation (PRPD) 


The phasing of partial discharges can be determined through state-of-the-art analysis methods. This makes it possible for you to assign the fault to diverse types of fault and to plan subsequent measurements as well as repair measures in a target-oriented and time- and cost-saving manner.
