Abstract

In the paper, on the basis of the symbolic method, mathematical identification of harmonic physical processes observed in a three-wire long line in stable operating modes was carried out, and a system of differential equations of a long line was obtained in a complex form. The result of the work reveals itself as a mathematical basis for further solving practical and theoretical problems of analysis and synthesis of directional three-wire electric circuits with distributed parameters. First of all, this applies to electric energy transmission lines, as well as communication lines, high-frequency radio engineering, television, information systems, etc.
