Lumped parameter models

Abstract

A review of the method used to calculate circuit component values for three-phase power lines leads to the identification of the first step; the derivation of a formula relating the capacitance of an isolated conductor to its length and radius. This formula can be regarded as a basic building block from which the capacitive parameters of multi-conductor assemblies can be derived. In computer terminology, a low-level object or operation from which higher-level, more complex objects or operations can be constructed is termed a primitive. So it seems reasonable to use the term primitive capacitance to identify the basic relationship.
