To limit the electromagnetic interference due to in-house PLC communication, standards on the emission levels of mains cables are now under elaboration. However, another additional aspect, not yet taken into account, deals with the possibility of exploiting the compromising radiated field to extract some information on the transmitted data. This problem of eavesdropping is known in the Electromagnetic...
Within the ICT OMEGA project, a thorough study of the Electro Magnetic Compatibility (EMC) issues linked to Power Line Communications (PLC) has been conducted. In this paper, we present our investigations carried out in the context of a frequency bandwidth extension of PLC systems up to 100 MHz. The current status of EMC regulations for PLC is first recalled. An experimental study is then presented...
In this paper, the physical phenomena of unbalance on the power mains network structure related to radiated EM fields caused by BPL signals, are discussed. It is shown that the unbalance of the power mains network is mainly responsible for this radiated emission when using the power mains for BPL (broadband over powerline) data transmission. The relationship between different unbalance parameters...
This paper proposes a new approach to modeling the radio frequency (RF) electromagnetic disturbances in broadband power line communication (PLC) networks using the multi-conductor transmission line (MTL) theory. The model includes a differential-mode (DM) current propagation model and a common-mode (CM) current propagation model. The frequency range of interest is from 1 MHz to 30 MHz. Practical measurements...
Different approaches are described for the characterisation of the low voltage mains network that is used for high-speed data transmission broadband over power line (BPL). Part 1 investigated the disturbance scenario of these BPL devices and importance will be given to develop a new measurement procedure in Comite Internationale Special des Perturbations Radioelectrotechnique (CISPR) to estimate the...
Experimental studies are carried out to investigate the effectiveness of solving the electromagnetic interference (EMI) problem in power line communication (PLC) networks. A test bed is designed to study the effectiveness of the method. Measurements are carried out in a semi-anechoic chamber using a clamp-on current probe, a rod antenna and a loop antenna to compare the conducted and radiated emissions...
