Résumé :

High Impedance Fault (HIF) detection is increasingly present in the concerns of distribution network protection. Practical methods to deal with HIFs are in great demand in the USA, where HIFs are not detected by conventional protection devices. The lack of aglobally accepted description of HIF is a drawback for HIF detection. In the effort to understand and explain HIFs we have performed a theoretical study, simulations, laboratory tests, and studied field recordings. The influence of certain factors has been studied by developinga ATP/EMTP simulation model and by defining laboratory tests. The drawn conclusions have been validated using HIF field recordings provided by Iberdrola Distribución Eléctrica S.A.U. In this paper, we present a complete HIF description and an explanation of HIF detection. This accurate characterization of HIF allowed the development of a pattern recognition method to detect HIFs.
