Телеграфні рівняння трипровідної довгої лінії (без урахування впливу поверхні землі)

Abstract

The article provides a mathematical identification of physical processes observed in a three-wire long line - a onedimensional electrical system with distributed parameters, builds a system of differential equations in partial derivatives, which, according to historical tradition, are called telegraphic equations. ves, which, according to historical tradition, are called telegraphic equations. The obtained results are a mathematical basis for further solving the problems of analysis and synthesis of threewire electric circuits with distributed parameters both in stable modes of operation and transient processes in them. This applies to three-phase electric power transmission lines, communication lines, high-frequency radio engineering, television, information systems, as well as electromechanical systems and transformers in the event of impulse currents and voltages acting on them, etc
