Abstract
Methods of testing at least a transmission line of interest within a group of transmission lines for anomalies using Time Domain Reflectometry are provided. The testing methods set forth herein aim to improve, for example, the quality and accuracy of information collected when propagating signals along a length of transmission line in order to pinpoint specific anomalies. To achieve this and other benefits, the testing methods simultaneously impose, for example, pulses of equal magnitude and form onto a group of transmission lines, such as the phases cables of a three phase power transmission cable system. From this, at least one transmission line from the group is monitored for reflected signals caused by impedance change. An example TDR is also provided.
