The document contains electrical parameters and power loss calculations for three different transmission line configurations transmitting 40 MW of power: a 33kV double circuit line, a 66kV line, and a 132kV line. It compares the current, conductor type, resistance, distance, power loss in Watts, and percentage power losses for each configuration using both 261 sqmm and 484 sqmm conductors over a 1 km distance. The percentage power losses are highest for the 33kV line at 0.375% and reduce progressively for the 66kV and 132kV lines.
