Smartgrid applications using narrow band power line carrier in underground power distribution systems. PLC Fault Locator

Within the scope of distribution automation, there is a wide range of applications that should work co-ordinately. As the devices supporting such applications are, in general, spread over a large part of the distribution network, one of the key issues to be considered is the communication, understood as: technology, equipment, protocols, standardization… Since equipment and functions are located at different hierarchical levels, they should be able to share information among them, no matter their relative position within the hierarchy. It is also important, in order to minimize restrictions, to have the possibility of using various technologies even to support the same application.
