Single Phase AC Circuit

Alternating Current (AC) is a type of electric power in which the electric current changes, both in magnitude and direction, at regular intervals. This AC Circuits can deliver power in either a Single Phase system or a Three Phase system.

Each line of a three phase system is suspended by a string of three similar insulators. If the voltage across the line unit is 16.5 kV, calculate the line to neutral voltage. Assume that the shunt capacitance between each insulator and earth is 1/8th of the capacitance of the insulator itself. Also find the string efficiency.

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.
