VERFAHREN UND VORRICHTUNG ZUR ÜBERTRAGUNG ZWISCHEN EINER VIELZAHL VON AN UNTERSCHIEDLICHEN ELEKTRISCHEN VERSORGUNGSNETZEN ANGESCHLOSSENEN LOKALEN EINHEITEN

摘要

A method for transmitting information between a plurality of local units (Mi) connected to several electricity distribution networks comprises transmitting information on one of the distribution networks by a modulated carrier current at a carrier frequency spaced from the distributed current frequency, and transmitting the information from one network to the other through a coupling device (14) which maintains the galvanic insulation between the networks.
