Generally, busbars are used in electrical transmission and distribution power. The presence of harmonic current in the busbar will generate more heat to the system. The generation of heat will be increasing power losses at the busbar and reduced their conductivity. A three-dimensional (3D) Finite Element Method (FEM) by COMSOL Multiphysics software was used in this research to analyze the heat distribution, average temperature, and power losses of copper busbar with 0.5 mm silver plating on their surface. The dimension of 30 mm × 4 mm × 500 mm copper busbar was utilized based on their suitable current carrying capacity from the measured location. The current source starts from 419 A and varies from 0% until 50% of Total Harmonic Distortion (THD) with an interval of 5%. The findings show improvement condition of copper busbar after silver plated on their surface. The bare copper busbar only meets the requirement range condition of BS159:1992 until the existence of 15% Total Harmonic Distortion of current (THDi) component while silver-plated copper complies until the maximum value of THDi which is 50%.

Busbars are generally used to transmit and distribute current to a distribution board in buildings. The existence of harmonic current has been known to increase heat generation in the bus duct system. The heat generation commonly causes power losses at the conductor. In this study, a three dimensional (3D) Finite Element Method (FEM) by COMSOL Multiphysics software was utilized for predicting the heat distribution and average temperature for each material and their compliance with BS159:1992 Standard. The dimension of the busbar in this work is 1.5×0.125×20. Current source begins from 410 A and varies from 0% until 50% of Total Harmonic Distortion (THD) with an interval of 5%. The results depict that the temperature varies between each material. Silver demonstrates the lowest operating temperature at an ideal current (0% THDi), and minimum temperature rise after the existence of harmonic component in the current source and iron depicts otherwise result. In Overall, copper proved to be the best material for busbar due to the reasonable price; the low operating temperature at ideal current; and less increment of temperature after the presence of harmonics in the current source.
