Method for indirect measurement of the phase capacitance of a distribution substation and the single-phase earth fault current

Abstract

This paper presents a theoretical justification for the possibility of determining the current of a single-phase earth fault in an indirect way, as well as a method for determining the line capacitance. An experiment was carried out to measure the current of a single-phase earth fault through a capacitive shunt. Comparison of calculated data and measured results is presented.
