ABSTRACT:
In a method, system and apparatus of measuring electrical power to consumers (16a–d) in a power distribution network (12), an electromagnetic field is sensed around at least one electrical conductor (12) in a power meter (30a–d) located at a consumer. The current flowing through the conductor is then derived from the sensed electromagnetic field. Instantaneous current values are stored in an electronic memory powered by the electromagnetic field. These instantaneous values or values derived from the instantaneous values are transmitted as digital information on the network to a receiver (20) provided at a distance from the power meter.
