Partial Discharge Testing – Essential for HV Asset Health
Partial Discharge (PD) testing is a key component of high-voltage asset condition monitoring. PD testing identifies early-stage insulation faults before they lead to catastrophic failures.
We design PD testing schedules based on the P-to-F curve, which measures the time between potential failure detection (P) and actual functional failure (F). This approach enables timely intervention via periodic testing or continuous monitoring, depending on asset risk and operational requirements.
Types of Partial Discharge
Internal PD: Occurs within insulation voids, silent but severe, often requiring Transient Earth Voltage (TEV) detection every two years.
Surface PD: Appears on insulator surfaces, often with crackling or ozone smells. Environmental factors may accelerate damage, requiring annual ultrasonic inspections.
Corona PD: Occurs around sharp conductors in gaseous environments. Outdoors it’s usually harmless, but in enclosed spaces, it can trigger surface PD—requiring regular monitoring.
