High Impedance Fault Modelling on 11Kv Feeder Using Matlab Simulink

Shyam Salona

Abstract: High impedance faults (HIFs) are serious and troubling disturbances on power distribution systems because the conventional power system protection devices are usually not designed to sense low fault current levels. In order to develop a HIF detection algorithm, we first need a HIF model. This paper presents a detailed model of HIF. Several institutions have already performed staged HIF tests in the past. Extracted characteristics from those tests has been used to design this HIF model. The proposed HIF model could replace staged faults which are quite tough to perform in order to get HIF data.
