ABSTRACT
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.

contact
systems
are
fundamental
components in a wide range of electronic devices and
power systems. These systems facilitate the transfer of
electrical current between conductive elements and
are crucial for ensuring proper functionality and
efficiency in various applications. However, electrical
contacts are susceptible to performance issues, such
as increased contact resistance and excessive heat
generation, which can compromise their reliability and
overall system performance.
The electrical-thermal behavior of electrical contact
systems is a complex interplay of electrical and thermal
phenomena. High contact resistance leads to power
losses, resulting in energy inefficiency and potential
overheating. The generation of heat in electrical
contacts can lead to thermal stress, material
degradation,
and
ultimately,
contact
failure.
Understanding the electrical-thermal behavior of
contact systems is crucial for optimizing their design,
predicting
their
performance
under
different
operating conditions, and ensuring their long-term
reliability.
This study aims to investigate the electrical-thermal
behavior of electrical contact systems using both
analytical and experimental approaches. The analytical
investigation
involves
the
development
of
mathematical models that describe the electrical and
thermal characteristics of the contact systems. These
models consider factors such as contact materials,
geometry, contact pressure, electrical current, and
environmental conditions. By employing mathematical
analysis, the study aims to predict the contact
resistance and temperature rise in the contact systems
under various electrical load conditions.
In addition to the analytical investigation, an
experimental approach is adopted to validate the
analytical models and gain insights into the actual
performance of the electrical contact systems.
Advanced
measurement
techniques,
such
as
thermography and electrical measurements, are
utilized to capture real-time data on temperature
distribution and electrical properties during contact
operation. The experimental data obtained from
various test setups and operating conditions are
compared with the analytical predictions, thus
providing valuable validation of the developed models.
By
combining
analytical
and
experimental
investigations, this study seeks to enhance the
understanding of the electrical-thermal behavior of
electrical contact systems. The findings will contribute
to the optimization and design of contact systems with
improved electrical performance and thermal
management. Ultimately, this research aims to address
the challenges associated with contact resistance,
power losses, and overheating in electrical contacts,
ensuring reliable and efficient operation in electronic
devices and power systems.
