Estimation of the line-to-line voltage phases in MV distribution faults using transformer inrush currents

Abstract: This paper proposes an innovative and comprehensive method using transformer measured inrush current during the first breaker re-close to add usefull information as fault location problem input. It is divided into the main following sections: Introduction, Magnetizing Inrush Current- A Brief Analysis, Voltage Phase Estimation Method and Conclusion. The authors insist on the importance and the availability of the fault data recorded by the line protection relay (oscillogram, COMTRADE file), with the transformer impedances knowledge, to accurately estimate voltage phases.
