4.1.4 Describing a smart meter configuration and its environment

Contrary to traditional stand-alone measurement equipment for utility metering, the configuration of a smart meter as a result of its definition includes certain interconnecting means and transmission related software.

Observing the assembly and its environment, the smart meter configuration can be considered as a network system and may contain a number of wired or wireless interconnected measuring instruments, which:

  • are used to measure different measurands;

  • are possibly installed quite close to each other; and

  • contain functions/modules that convert the measured values into binary numeric electromagnetic quantities which become available as so-called digital signals.
