Partial discharge Source Calibration of Radiated Partial Discharge Signals

open access: yes2022 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.
