Thermal analysis and optimization of temperature rise in busbar joints configuration by FEM

The busbar systems are introduced, typically in industries for large scale power distribution. As a high power distribution with large current raises heat loss and temperature rise problems at busbar joints. This paper deal with thermal analysis of various joint configurations of high power busbar system and shows how the temperature can be reduced by introducing slots in true contact area. The finite element method is employed for thermal analysis and simulation is carried out with ANSYS multi physics software. The simulation results are compared with experimental solutions.
