ABSTRACT
This chapter analyzes the series resistance, series inductance, and shunt capacitance for three-phase power lines. Transmission of electric power is the key for the development of the modern electric system in the world. The transmission tower is the supporting unit for overhead transmission lines carrying the transmission cables at a safe height from the ground. For modeling transmission lines, it is necessary to establish physics that give them their electrical characteristics, so a precise model can be developed. The chapter discusses resistance, inductance, and capacitance for a solid non-magnetic conductor. Capacitance of transmission lines comes from the electric field resulting from a charging charge flowing through conductors. The chapter presents the equivalent ABCD model, which relates the voltage and current of one side of the transmission line with the voltage and current of the other side.
