Description
Summary:Partial Discharge (PD) measurement and characterization provide vital information on insulation condition, different aspects of insulation ageing useful for equipment integrity verification and diagnosis. The PD denotes the Life vs. Stress characteristics of the material. The PD phenomenon is manifested as observable electric pulses. The work demonstrates the principle of PD measurement with the aid of an Off-line test arrangement. This paper investigates on the PD Inception and Extinction Voltage and determines the apparent charge, discharge energy and power dissipation for discharge quantity at a specified voltage. PD detection and measurement procedures suitable for use on Surge Arresters, Current Transformers and Insulators are examined.
