Note that volume of conductor and hence weight required is less in case of 3 phase 3 wire system Example 7 6 A sub station supplies power at 11 kV 0 8 pf lagging to a consumer through a single phase transmission line having total resistance both go and return of 0 15 The voltage drop in the line is 15 If the same power is to be supplied to the same consumer by two wire d c e by a new line having a total resistance of 0 05 and if the allowable voltage drop is 25 calculate the d c supply voltage
