A two-core feeder 138 kilo meter long supplies a maximum current of 142 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 4 months. The resistance of conductor 1 km long and 1mm² section of conductor as 0.0371 ohm. The value of area of cross section is 120 mm2. The cost of energy is 15
