EMP/EMI Hardening of Electrical Conduit Systems

Abstract

Properly designed and installed conduit systems can provide an effective EMP/EMI hardening technique for fixed facility construction. This report presents the results of a CERL study to provide design criteria and to conduct hardness assessments for such shielded systems. Leakage mechanisms are identified, and techniques for determining signal levels coupled to conductors inside conduit systems are presented. EMP shielding properties of conduit hardware items are analyzed and some experimental EMP hardened conduit hardware items evaluated. Finally, a number of 'in situ' test techniques for identifying and locating EMP-related defects in an installed conduit system are assessed.
