-This paper presents an analysis of electromagnetic immunity of energy metering devices, using broadband power line communications (PLC) in low voltage (LV) supply networks with high levels of disturbance. Several tests have been carried out to characterize the behavior of PLC modems and couplers in presence of the most common types of disturbances and electromagnetic interferences (EMI) which can be expected in LV distribution networks. The method exposed allows repeat the tests with different modems, communications wires and couplers. Thus it is possible to compare different elements between them and choose the best for every occasion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
