ABSTRACT:
A method and apparatus of detecting an anomoly along an elongate, electrically conductive member comprising the steps of. An electrical pulse is so sent along the member from each of two locations towards an intersecting location between the two locations that the pulses intersect and are modified at the intersecting location. At least one of the modified pulses is analyzed to determine whether an anomoly exists at the intersecting location. The timing of at least one of the pulses is based at least in part on the propagation delay of an electrical pulse propagating between the two locations.
