Offline Partial Discharge Testing for HV and MV Cables
Offline Cable PD Mapping Service™: Assess the health of MV/HV cables through VLF testing and Tan Delta measurement
The Cable PD Mapping Service™ is an accurate method that assesses and reports on the health of MV and HV cables. It effectively locates issues within individual HV cables, allowing for prompt repair and resolution.
Test techniques used:
- Offline Very Low Frequency (VLF) Testing
- Tan Delta Measurement
Our state of the art Very Low Frequency (VLF) Cable PD Mapping test equipment can be used to determine cable condition in new installations or during a scheduled shutdown.
The HV test gear we use allows us to accurately determine PD magnitude and location along the length of the cable. This allows the cable owner to manage their assets with increased confidence through recommendations such as regular monitoring and localised repairs to sections where discharge is found.
‟Our system is safe, non-destructive and has a 30-year track record of success within Australia and globally.”
Benefits
- Locate PD activity before it leads to failure
- Ideal for pre-commissioning or post-repair
- Reduce the need for expensive excavations by accurately identifying the problem area
- Reduce the risk of unplanned, expensive outages
Features
- Identify and locate PD activity through time-of-flight measurement
- Works with paper or polymer insulated high voltage cables
- Produce a detailed map of cable condition and PD problems
