23 Ιουν 2023 · The complete development of transmission line theory is presented in Section 2.2.2, and Section 2.2.3 relates the RLGC transmission line model to the properties of a medium. The dimensions of some of the quantities that appear in transmission line theory are discussed in Section 2.2.4.
A transmission line is a wire with a uniform goemetry along its length: the capacitance and inductance of any segment is proportional to its length. We represent as a large number of small inductors and capacitors spaced along the line. The signal speed along a transmisison line is predictable.
Transmission line: a bridge between circuit theory and electromagnetic theory. By modeling transmission lines in the form of equivalent circuits, we can use Kirchhoff’s voltage and current laws to develop wave equations whose solutions provide an understanding of wave propagation, standing waves, and power transfer.
Transmission Lines. Transmission and distribution of electrical power occurs over metal cables. Overhead AC or DC. Underground AC or DC. In the U.S. nearly all transmission makes use of overhead AC lines. These cables are good, but not perfect, conductors. Series impedance. Shunt admittance.
