Abstract

The presence of connectors or other shield interruptions can seriously degrade the EMI protection provided by the braid of an otherwise well-shielded cable system. The paper presents a methodology to determine the internal response of a discontinuous shielded cable to an exciting electromagnetic field. The analysis is performed considering different types of discontinuities such as cable connectors, pigtail terminations, and interrupted shield. For the specific case of a cable with the shield interrupted at the middle, the theoretical results have been compared with experimental data obtained using a bounded wave EMP simulator

Electromagnetic compatibility

Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage to operational equipment. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering.

Electromagnetic shielding

In electrical engineering, electromagnetic shielding is the practice of reducing or blocking the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs (). Electromagnetic shielding that blocks radio frequency (RF) electromagnetic radiation is also known as RF shielding.

Electrical connector

Components of an electrical circuit are electrically connected if an electric current can run between them through an electrical conductor. An electrical connector is an electromechanical device used to create an electrical connection between parts of an electrical circuit, or between different electrical circuits, thereby joining them into a larger circuit. Most electrical connectors have a gender - i.e. the male component, called a plug, connects to the female component, or socket.
