A meter arrangement includes a measuring unit. The measuring unit is configured to be coupled to a phase of a power line, to measure at least one parameter of the phase and to provide data representing the measured parameter. A control unit is coupled to the measuring unit and is configured to process the data provided by the measuring unit. A data communication channel is configured to couple the measuring unit and the control unit and provides a path for data transmission between the units. The data communication channel includes a magnetic transfer device. A power channel is configured to couple the measuring unit and the control unit. A path for energy transmission is provided between the measuring and control units. The power channel includes a magnetic transfer device.
