ABSTRACT:
A system for analyzing electrically conductive members such as pipelines, in which electrical pulses are transmitted through said member to intersect at predetermined locations. At least one of the pulses which intersects the other pulse is analyzed to determine whether there is a variation in the intersecting pulses at locations along the length of the member. With the member being tested being a pipeline, in some embodiments, a direct current is applied to the pipeline and this also is used to analyze the condition of the pipeline and also the information provided by the intersecting pulses. Amplitude, frequency, and wave form variations of the intersecting pulses are analyzed to detect anomalies or other conditions along the pipeline or other member.
