Investigation of the Partial Discharge Inception and Flashover With IEC‐Based Comparative Tracking Index Electrodes and Comparison With Homogeneous and Inhomogeneous Electric Fields at Varying Pressures for Aerospace Applications

High Voltage, EarlyView.
ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.

Analysing the Impact of Frequency Bands on Partial Discharge Measurement Outcomes in Generators Through Model‐Based Approach

High Voltage, Volume 11, Issue 2, Page 351-359, April 2026.
ABSTRACT The electromagnetic wave produced by a partial discharge (PD) covers a broad range of frequencies, from a few kHz to several 100 MHz. Because of the nonlinear response of the stator winding, each frequency component of the PD pulse experiences different levels of attenuation as it travels through the winding structure. Consequently, the choice
