Distribution automation using distriubution line carrier systems. Mains signalling requirements - MV phase to earth and screen to earth coupling devicesWhat is BS EN 61334 3 22 Distribution line carrier systems about? BS EN 61334 3 22 is applicable to MV phase to earth capacitive and screen to earth intrusive inductive coupling devices for medium voltage (MV) distribution line carrier (DLC) systems. The object of BS EN 61334 3 22 is to establish definitions, requirements, methods of testing and rated values for phase to earth capacitive and screen to earth intrusive inductive coupling devices to be
