Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model

IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.
Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.

Multiphysics Finite Element Analysis of Wire and Ribbon Bonds Under Pulse Power Loads

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
Multiphysics finite element analysis was used to highlight reliability issues with aluminium wire bonds specific to pulse power applications. The high conduction currents impose large Lorentz forces on the wire bonds, excessively stressing the wire bond–die interface. A preliminary aluminium ribbon bond solution was provided and analysed.
