Abstract:

Partial discharge (PD) incidents may occur within critical components of high-speed rail electric systems, including transformers, motors, and switchgears. These incidents result from localized defects compromising insulation, unable to withstand electric stress, leading to flashovers. PD propagates and escalates over time, with potentially severe consequences including catastrophic breakdowns, unplanned downtime, and safety hazards. Fortunately, PD activities emit radio frequency (RF) signals, prompting the development of a hardware platform for non-invasive, non-disruptive real-time PD detection and continuous monitoring in high voltage transformers and switchgears within high-speed rail systems.
