Abstract

See full text

A methodology for decomposing a three-wire equivalent circuit into a cascade arrangement of a two-wire transmission line and a three-port terminating network is disclosed. Decomposition synthesis is accomplished by iteratively separating the equivalent circuit into the two component parts according to a predetermined algorithm and then comparing the derived three-port network to each network within a class requiring identification, thereby effecting an identification whenever a match occurs. Upon a matched condition, the resistance of the transmission line corresponds to the distance to the terminating network and may be used for fault diagnosis purposes.
