Abstract
This study examines the Partial Discharge (PD) performance of aircraft cables using a specially designed test electrode. Electrode positioning was precisely controlled within an atmospheric chamber to replicate coaxial geometries. Long exposure imaging reveals useful insights that enhance our understanding of PD behaviour at varying atmospheric pressure. The research compares the experimental data with existing mathematical models based on the Paschen and Halleck equations revealing notable inconsistencies, particularly at higher pressures. This work contributes valuable insights into the complexities of PD phenomena in aircraft cables and proposes a new model by enhancing an existing predictive model and incorporating the influence of an insulation barrier.
