Information gained through Partial Discharge Testing and Monitoring can provide important information on the quality of insulation, and its impact on the overall condition of the equipment.
Since PD activity is frequently present well before insulation failure, it can be monitored over time, and repair or replacement of the asset can be done as necessary.
PD Testing can help predict future performance and reliability of critical equipment, such as:
- Cables, splices, and terminations
- Power transformers and bushings
- Motors and generators
