Aim of the study is to determine and compare the electromagnetic induction and earth conduction effects on buried passive conductors caused by phase-to-ground faults in a MV underground cable distribution system without ground wire. For the scope a software program has been developmed based on a multiconductor analysis. The procedure is based on a fine discretization of the system into small elementary cells which are described in terms of lumped parameters evaluated on the basis of Carson's theory.

Abstract
Aim of the study is to determine and compare the electromagnetic induction and earth conduction effects on buried passive conductors caused by phase-to-ground faults in a MV underground cable distribution system without ground wire. For the scope a software program has been developmed based on a multiconductor analysis. The procedure is based on a fine discretization of the system into small elementary cells which are described in terms of lumped parameters evaluated on the basis of Carson's theory.
