Partial Discharge Testing — Essential HV Asset Health Assessment
At Tex At Site, partial discharge (PD) testing is a vital component of our high-voltage asset condition monitoring services. It plays a key role in identifying early-stage insulation faults before they escalate into catastrophic failures. To design an effective PD testing schedule, we begin by analysing the P‑to‑F curve—the time between potential failure detection (P) and actual functional failure (F). As a result, this approach enables timely fault detection and intervention, which can be achieved through either periodic testing or continuous monitoring, depending on the asset’s risk profile and operational demands.
Understanding Partial Discharge Types
Partial discharge (PD) falls into three primary categories: internal, surface, and corona.
Internal PD, which occurs within insulation voids or cavities, is silent but severe. It shows no immediate warning signs such as noise, smell, or visible discharge, often leading to sudden equipment failures. Therefore, techniques like Transient Earth Voltage (TEV) detection—typically performed every two years—are essential for early identification.
Surface PD appears on insulator surfaces and is usually accompanied by audible crackling or ozone smells, indicating insulation degradation. Moreover, environmental factors like humidity and pollution can accelerate damage, shifting inspection frequency from biennial to annual, often using ultrasonic methods.
Corona PD occurs around sharp conductors in gaseous environments and, while generally harmless outdoors, can trigger surface PD in enclosed spaces. Consequently, regular monitoring is crucial to prevent escalation into more serious insulation failures.
