Calibration of free-space radiometric partial discharge measurements [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2017 The present study addresses the calibration of four types of partial discharge (PD) emulators used in the development of a PD Wireless Sensor Network (WSN). Three PD emulators have been constructed: a floating-electrode emulator, and two internal PD emulators.

DEVELOPMENT AND CALIBRATION OF A MICROCONTROLLER BASED PARTIAL DISCHARGE CALIBRATOR
Electrica, 2016 Partial discharge is an instantaneous energy release depending on a charge accumulation caused by an electric field localized in any section of insulation materials. In this phenomenon, there is no observation of full discharge but electrical perforation

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.

Precision Calibration System for Partial Discharge Calibrators
Proceedings of the Nordic Insulation Symposium, 2019 Partial discharge calibrators need to be periodically calibrated traceable to national standards. VTT MIKES, the National Metrology Institute (NMI) of Finland, has official expertise to calibrate the apparent charge of PD calibrators from 1 pC to 100 nC according to IEC 60270.
