Strategies in the Topological Approach to Electromagnetic Interference Control.
Abstract
The ability of standard commercial equipment cabinets to be used to provide a electromagnetic interference is explored. The internal to external, and external to internal, electromagnetic isolation provided by various configurations of cabinet-penetrating conductors was measured at frequencies from 20 HZ to 20 MHZ. Excellent isolation was obtained over the entire frequency range when penetrating conductors (coaxial cables, grounds buses, power conductor green-wires, and power conductor black and white wires) were installed in accord with barrier principles. Little or no isolation was obtained with the direct penetration of the cabinet by conductors. These results were confirmed by laboratory and field measurements (at operating CDAA sites). Keywords: Electromagnetic interface control; Electromagnetic Compatability; Topological approach; Grounding; Coaxial cable coupling; Green wire barrier plate.
