Zusammenfassung:A utility meter (1) is described comprising a metering section (2), a communication interface (3), and a communication path (4) providing a galvanic isolation between said metering section (2) and said communication interface (3). Such a utility meter should be operated with low power consumption. To this end said communication path (4) comprises a transformer (5) having a primary side with a first primary terminal and a second primary terminal connected to said metering section (2) and a secondary side (S) connected to said communication interface. 描述了种公共事业仪表(1),其包括:计量部(2)、通信接口(3)、以及提供所述计量部(2)与所述通信接口(3)之间的电流隔离的通信路径(4)。这种公共事业仪表应该以低功率消耗来操作。为此目的,所述通信路径(4)包括具有初级侧和次级侧(S)的变压器(5),该初级侧具有连接到所述计量部(2)的第初级端子和第二初级端子,并且该次级侧连接到所述通信接口。
