Electrical contact systems play a critical role in various electronic devices and power systems, and their reliable performance is essential for ensuring efficient electrical transmission and preventing overheating issues. This study presents an analytical and experimental investigation of the electrical-thermal behavior of electrical contact systems. The analytical approach involves the development of mathematical models to predict the electrical and thermal characteristics of the contact systems under different operating conditions. The experimental investigation utilizes advanced measurement techniques to validate the analytical models and gain insights into the contact system's actual performance. Factors such as contact resistance, electrical current, contact pressure, and environmental conditions are analyzed to understand their influence on the electrical and thermal behavior of the contacts. The findings of this study contribute to the optimization and design of electrical contact systems, leading to enhanced performance, reduced power losses, and increased reliability in electronic and power applications.
