Medium Voltage Underground Fault Localization using CelloC System

Abstract

This paper addresses a medium voltage (MV) underground fault localization system (UFLS), which is capable to accurately pinpoint the location of a fault occurred on an underground cable. The localization process is performed on an offline faulty cable. The paper discusses the concept and the design of version v2b of UFLS CelloC, developed by a research team of Research Center of Hydro-Québec (CRHQ), and the results of the tests performed in laboratory or carried out on Hydro-Quebec’s MV network.
