This course is designed to provide participants with a detailed and up-to-date overview of electrical equipment partial discharge monitoring. It covers the fundamentals of transformer, switchgear and cable; the parts/design and failure mechanisms; the PD theory, PD as a symptom, partial discharge or corona, void formation and electrical discharges; the insulation types and causes of deterioration including the dielectric stress, capacitive coupling and causes of PD; and the types of PD, controlling stress, preventing PD and PD monitoring and detection.
Further, this course will also discuss the test equipment, PD emissions and radio waves; the physical signs of PD, basic wave theory and types, electromagnetic wave theory, acoustic waves, ultrasound and transient Earth voltage principles; the airborne and contact mode, TEV generation and ultrasonic generation, propagation and detection; and the signal attenuation, surface and internal discharges, directional antennas, noise cancellation, PD pattern and time of flight.
During this interactive course, participants will learn the PD detection in cables, PD detection in transformers airborne and PD detection instruments; the UltraTev, UltraTev Plus+, UltraTEV locator and PD hawk; the accessory package, noise, background interference and substation environments; the different types of PD test and survey; and the data interpretation, applicable standards, data presentation, trend analysis, polarity predominance, load effect and temperature effect.
