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.

Principles of Charge Estimation Methods Using High-Frequency Current Transformer Sensors in Partial Discharge Measurements. [PDF]
Sensors (Basel), 2020 This paper describes a simplified model and a generic model of high-frequency current transformer (HFCT) sensors. By analyzing the models, a universal charge estimation method based on the double time integral of the measured voltage is inferred.

The Proposal of a New Tool for Condition Assessment of Medium Voltage Power Cable Lines
Energies, 2021 A medium voltage (MV) cable network is a substantial component of the distribution network. Present management of this grid segment is mainly based on the failure rate analysis, i.e., a rise in the number and kind of faults on the actual line means that ...

Partial discharges characteristics study in XLPE cable insulation with multiple defects [PDF]
Омский научный вестник, 2021 The paper simulates the electric field intensity picture in the cable with one and several defects. Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with
