A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load. (b) The power loss due to the line impedance. (c) The power factor angle of the load. (d) The line-to-neutral voltage of the line at the receiving end. (e) The voltage drop due to the line impedance. (f) The line-to-line voltage of the line at the sending end
