The span between two level supports for a 132 KV overhead transmission line is 200 The weight of conductor per meter length is 2 kg while the tension in the conductor is 2250 kg. Calculate the slant sag and the vertical sag if the wind pressure per meter length and the weight of ice per meter length of conductor are 1-8 kg and 1.2 kg respectively.

Q1. Transmission and distribution lines are important components of any power system study.   (A)        In relation to high voltage overhead ac transmission lines,   Discuss the choice of materials for the conductors in terms of their electrical/mechanical properties and the costs involved. Discuss the factors that determine the distance (D) between phase conductors and explain the impact of the distance D on the inductance and capacitance values of the line at different voltage levels. Support your arguments with relevant equations where appropriate. Discuss the impact of the radius of the conductors on phase capacitance and inductance values and why bundles are used at very high voltages.
