Abstract
A system or method of analyzing a conductive member for the presence an anomaly. A conductive pipe member is analyzed for the presence an anomaly the electromagnetic properties of which are non-linear. The electromagnetic properties of the pipe member at the anomaly are altered by applying a direct current perturbation signal to the pipe member. At least one test source signal is applied to a first test location on the pipe member remote from the anomaly to cause the at least one test source signal to travel along the pipe through the anomaly. At least one test return signal associated with the at least one test source signal traveling through the anomaly is detected. The at least one test return signal is analyzed for characteristics associated with the anomaly.
