Abstract

An apparatus is provided for conveying electrical power and data signals between a first location and a second location in a well borehole. The apparatus comprises a first drill pipe disposed at the first location, and a second drill pipe disposed at the second location. A second end of the second drill pipe is coupled to a first end of the first drill pipe. A first plurality of conductive pathways such as insulated wires extend longitudinally through at least a portion of the first drill pipe and terminate at the first end. A second plurality of conductive pathways extend longitudinally through at least a portion of the second drill pipe and terminate at the second end. A verification device is operatively associated with the first and second pluralities of conductive pathways for verifying electrical continuity between the first and second pluralities of conductive pathways.
