Abstract: 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.
