Modeling of Resistance of Granulated Current-Conducting Mediums by Parametric Dependences

ZAKHARCHENKO S.N., SHIDLOVSKAYA N.A.

ABSTRACT

The model of equivalent electric resistance of the granulated current-conducting mediums at their spark-erosional processing has been created on the basis of experimental data and analysis of physical processes in such mediums. The offered model considers the phases of occurrence, de¬velopment and fading of spark channels which, in turn, are caused by dynamics of generation and recombination of free charge carriers in them.imization of distribution networks reliability, which are most suitable for the domestic power companies.

KEYWORDS

Electricalresistance, granular conductive medium spark channels parametric model.
