Field Pattern and Associated Losses in Aluminum Sheet in Presence of Strip Bus Bars

The calculation of eddy-current losses in aluminum sheets of definite and infinite thickness in the presence of bus bars carrying heavy currents is presented. The expression for losses has been developed; a digital computer has been used to calculate the losses for several particular cases. Various curves are plotted to make the results readily available for practical use. The investigation indicates a thickness of conductor sheet in proximity to a bus bar which causes minimum loss due to eddy currents induced in it.
