Partial Discharge (PD) occurs when electrical discharges take place inside medium and high voltage insulation due to imperfections in the system (flaws, cracks, voids, irregularities).
These weaknesses create voltage stresses and cause eventual failure of the insulation characterized by small but detectable releases of energy or PD.
Types of equipment subject to Partial Discharge:
- Bushings
- Cables
- Capacitors
- Circuit Breakers
- Generators
- Instrument Transformers (CT’s, PT’s)
- Insulators
- Motors
- Surge Arrestors
- Switchgear
- Transformers
Data acquired through PD Testing and Monitoring provides important information on the quality of insulation, and its impact on the overall condition of 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.
Protec carries a full line of PD equipment, available for rent today.
