Modeling Thermal Effects in Electromagnetic Fields in a typical ۱۳۲ kv cable line configuration

This study extends the inductive effects model by incorporating thermal effects, specifically a temperature-dependent electrical conductivity modeled through linearized resistivity. A multiphysics coupling between electromagnetic fields and heat transfer is achieved using a frequency-stationary study approach. The influence of elevated temperatures on the ohmic losses in conductors, screens, and armor layers is investigated and verified. The resulting temperature distribution is then applied in the inductive effects model to perform a first-order temperature correction. Finally, the results are investigated.
