Basic contact line electrical parameters of the electrified track

Abstract

The paper summarizes basic electrical parameters of the contact line from the viewpoint of possiblesimplification at particular calculation. Three modes are discussed, e.g. homogeneous line, two-port network and substitution with simple L or C. The calculations based on homogeneous line theory appear as the most preferable, the use of two-port network theory appears preferable for contact line design of labor model. The third mode is adequate for calculations up to approx. 400 Hz.
