Time domain measurement of shielded cables with connectors

Abstract

For an IEMI/HEMP hardened building, external cabling should be enclosed in shield to protect against coupling of high-level transients. The US military standard requires solid conduits, with welded end connections. This paper discusses the use of time domain (transient pulses) laboratory measurements of the protection provided by the cable and connector shielding. Sample results are shown for shielded cables that use non-welded end connections.
