Suppression Measures of Partial Discharge at Rod–Plate Connection in Composite Tower
Energies, 2023 Rods and plates at the connections in composite insulating material towers are commonly fixed to each other by metal bolts, which may cause electrical field distortion at the connections. So, the rod–plate connections are prone to partial discharge under

Partial Discharge Localization in Power Transformers Using Invariant Extended Kalman Filter
IEEE Transactions on Instrumentation and Measurement, 2023 This article proposes a novel invariant extended Kalman filter (IEKF), a recently modified version of the extended Kalman filter (EKF), to estimate partial discharge (PD) location in a transformer insulation system model.

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.
