Abstract:
1. A method of testing a transmission line for an anomaly, comprising: providing a group of parallely extending transmission lines, each transmission line comprising first and second conductors, the group of parallely extending transmission lines including a test transmission line and one or more associated transmission lines; generating at least one test pulse of energy; simultaneously imposing the at least one test pulse of energy onto the test transmission line and the one or more associated transmission lines, the pulses imposed onto the transmission lines having equal magnitude and form and travel along the transmission line's length; and receiving at least one reflected signal from at least the test transmission line, the at least one reflected signal resulting from the test pulse interfacing with an anomaly along the test transmission line; wherein the test transmission line is a single phase of a multi-phase power transmission cable and the one or more associated transmission lines comprise the remaining phases of the multi-phase power transmission cable.
