    摘要: A remote metering system comprises a multi-phase mains supply system (10) having a control unit (CS) and a plurality of single-phase consumer meter units (M1-M3) with messages passing between the meter units and the control unit. For phase determination, the control unit and each meter unit includes synchronizing means (CTR1) for synchronizing its message processing to its phase of the mains supply (or one particular phase, for the control unit). The relative phases of the control unit and a meter unit can then be determined, by a comparator (17), from the timing of a message passing between them relative to the phases to which those units are synchronized.
