On the Calculation of Economic current Density of Aluminium Cell Busbars

The calculation of economic cross section for D.C. busbars, based on the minisation of total costs e.g. cost of conductor and a stream of costs for power losses in the conductor, is quite well known. Certain complications arise in quantifying the cost of conductor and cost of the power lost. In the literature it is customary to express the cost of conductor in terms of an equivalent annual cost.
