A Reduced Model of Reflectometry for Wired Electric Networks

Abstract : With the fast development of electric and electronic components in modern engineering systems, the reliability of electric transmission lines (TL) is becoming a crucial issue. The increasing number of electric connection failures requires research on diagnosis technologies. For example, advanced reflectometry, by analyzing the reflection of electric waves observed at one end of a TL, provides an efficient solution for the diagnosis of hard faults (open or short circuits) in a single TL, whereas the diagnosis of soft faults in wired electric networks is still an open problem. The purpose of this paper is to study a reduced mathematical model of wired electric network, which will constitute a basis for the development of methods for soft fault diagnosis. The proposed model is also useful for numerical simulation of the studied networks, by computing reflection coefficients, as well as voltage and current waves.
