Radio-Frequency Propagation on Polyphase Lines

Component analysis is widely used in the solution of power frequency problems and is also adaptable to radio-frequency (r-f) problems on multiconductor overhead lines. The appropriate component sets (modes) for radio frequency are a function of the line geometry. Matrix methods can utilize these components in the solution of r-f propagation problems involving complex systems and including effects of transposition, ground wires, intermediate faults, and general impedance terminations.
