Inspecting for Corrosion of Shipboard Conduits and Shield-to-Ground Adapters with Low-Bandwidth Pulsed-Current Injection

Abstract

We inspected metal conduit with a low-bandwidth, pulsed-current injection. This technique, called the L/R method, has been used successfully to identify corroded cable shields on aircraft, armored vehicles, and fixed and mobile communications systems. We successfully applied this technique to the inspection of shipboard electromagnetic protective conduit. The application of this technique is described in detail and the experimental results are presented.
