Partial discharge Source Calibration of Radiated Partial Discharge Signals

2022 2nd International Conference on Advance Computing and Innovative Technologies in Engineering (ICACITE), 2022
Based on the IEC 60270 guideline, a galvanic quantification along with free-space radiometry (FSR) method are used to measure partial discharge (PD) simultaneously. The PD source is a floating-electrode emulator type that was custom built. Sources are powered by AC or DC, power supplies. A biconical antenna captures the emitted a signal.

Modeling partial discharge phenomena

IEEE Electrical Insulation Magazine, 2020
Measurements of partial discharge (PD) activity are a commonly used technique to diagnose the health of insulation material within high voltage plant. The definition of PD is relatively broad, it is generally defined as a localized or confined discharge within an insulating medium [1]. Due to the high electric breakdown strength of insulation materials,
