my brother are saying right in above ans.. but not fully right...just first u have to take one by one phase asume for R phase... as per length just u calculate its resistance..which is alerady decided by per km for any type of conductor...like..panthar , zebra as so onnn///and after that find how many electrical power will be delevered for in same circuit...... now its very easy....losses in single phase = IxIxR..............where for I u have to just devide power / potential votage of transmission lines.....................
