The cost of a single phase overhead feeder is OMR 7 a per km ( a is area of cross section in sq mm) and the interest and depreciation charges on feeder are 10%. Determine the most economical current density to use for distribution requiring full load current of 75% of the year. The cost of generating electrical energy is 12 baisa per unit. Assume resistance of 1 m length and 1 mm2 section of conductor as 1/62 ohm. Current density =. LA/mm2
