Electrical Contacts Under Thermal and Electrical Stress: Analytical and Experimental Investigations

Abstract

Electrical contacts play a crucial role in various electrical and electronic systems, where their performance is significantly influenced by thermal and electrical stresses. This study presents a comprehensive investigation into the electrical-thermal behavior of electrical contacts using both analytical modeling and experimental validation. The analytical approach involves the development of mathematical models to predict contact resistance, temperature rise, and degradation mechanisms under different loading conditions. Experimental studies are conducted to validate the theoretical predictions and provide insights into material behavior, contact wear, and failure mechanisms. The findings highlight the interplay between electrical and thermal effects, emphasizing the importance of contact material properties, surface roughness, and environmental conditions. This work contributes to the optimization of electrical contact design for improved reliability and efficiency in practical application.
