Abstract
A system and method for locating flaws in cable shields and electromagnetic tubing (shield conduit) without disconnection of the cable or conduit under test is described. The fault location method, using a unique sensor array and fault detection circuit, supplements capabilities of earlier inductance/resistance tester. Previous inductance/resistance testers allow the user to measure very small resistances at cable/connector joints, usually without disconnecting the circuit under test.
