Abstract
The influence of electromagnetic radiation from power-line communication (PLC) systems on various types of communication or broadcast services has been investigated. This paper describes experimental results of the influence of electromagnetic radiation from a PLC system on other communication services. The influence was evaluated by measuring the current induced in a communication cable close to a power-line cable. The evaluation involved measuring the induced current for different communication cable structures, different lengths over which the communication and power-line cable ran parallel, and different distances of separation between the cables. It was found that the induced current that occurs in the adjacent communication cable depends on the length over which the cables run parallel and the distance of separation, but does not depend on the structure of the communication cable. Furthermore, the minimum length of parallel cabling to result in saturation of the induced current, which depends on the output power of the PLC modems, was obtained experimentally.
