What is Partial Discharge?
Partial Discharge (PD) is a degenerative phenomenon that affects the electrical insulation of medium voltage (MV) & high voltage (HV) equipment.
PD is the best early warning indicator of electrical insulation degradation in assets operating at 3.3 kV and above.
PD testing and monitoring supports Condition Based Maintenance programmes – enabling operators to improve their asset reliability and avoid unplanned outages.
By providing a condition assessment of their in-service assets, HVPD help operators avoid in-service failures, reduce unplanned outages and improve their maintenance efficiency – saving them time and money.
Our Partial Discharge Technology
We supply a comprehensive range of equipment to detect and monitor On-line PD for the condition assessment of in‑service power cables, switchgear, motors and generators, and transformers rated at 3.3 kV and above. Suitable for MV, HV and EHV assets, our PD testing and monitoring technology provides you with an early warning of developing insulation faults, helping you to avoid costly failures and resulting unplanned network outages.
