Bus-bars are a vital component of electrical circuit ranging from high current to low current applications. The individual phases of busbar are found to be arranged in different configurations. They are mounted in an enclosed chamber. However the different configurations lack support in terms of standards or empirical data. As such, no particular configuration is known which is optimum or best suited. The current flowing through the busbar will lead to generation of heat due to the material resistance, which needs to be dissipated effectively. Natural convection is the only mode of heat transfer within the chamber. The inefficient heat dissipation affects the longevity of the busbar. In the present study, computational simulation of bus-bars in a closed chamber is done by using CFD tool. Comparison of the heat dissipation characteristics and temperature distribution is done for different configurations. Based upon these, the optimum configuration is identified.
