What is a partial discharge?

Partial discharge (PD) is a form of electrical breakdown that happens when only a portion of the insulation between two conductors is compromised.

This leads to a localized increase in electrical current, potentially damaging the surrounding insulation.

While partial discharge can occur in any electrical equipment, it is most frequently observed in high-voltage equipment like transformers, generators, and cables.

Advantages of PD monitoring

• Increased operational reliability and security of supply of electric energy
• Significantly decreases the power outage periods and frequencies
• Helps to predict remaining system (cables) lifetime and decrease costs on new devices installation

• Saves operational/prophylactic costs
• Decreases CO2 emission production
