Contents

For the calculation of overhead transmission line impedances with earth return Dubanton has given explicit formulae based on the assumption, that the earth return current is concentrated in a plane being in a fictitious complex depth. In this paper the authors give the mathematical basis started from Carson's formulae and the physical interpretation of this heuristic method.

Übersicht

Für die Berechnung von Freileitungsimpedanzen hat Dubanton explizite Formeln vorgeschlagen, deren Grundlage die Voraussetzung ist, daß der in der Erde zurückkehrende Strom in einer Fläche konzentriert gedacht werden kann, die sich in einer fiktiven komplexen Tiefe befindet. In diesem Artikel werden der mathematische Hintergrund, ausgehend von Carsons Integralformed, dargestellt und eine physikalische Interpretation dieser intuitiven Methode gegeben.
