A two-core feeder 156 kilo meter long supplies a maximum current of 107 A at 400 volts. The demand is such that the copper loss per annum is that which would be produced by the full load current flowing for 8 months. The resistance of conductor 1 km long and 1mm section of conductor as 0.0761 ohm. The value of area of cross section is 120 mm?. The cost of energy is 15 baisa per unit. Find the power loss and Annual cost. Power Loss = kW Annual cost = Rial
