Hi, last time I told you about smart meter on middle voltage ; this time let’s see the basics of smart meter on low voltage.

Low is considered a voltage up to 1kV. There are two ways for measuring on low voltage:

  • Direct measuring – this method is used for current up to 100A (there are one phase and three phase electricity smart meters for this type of measurement)
  • Indirect measuring – this method is used for current over 100A (you need current transformers for low voltage)

Direct measuring

In the following pictures you can see how the different electricity smart meters look like depending on the measurement method.

These smart meters are to be mounted on small electricity consumers like small houses, apartments, small shops.

Hi, this is Steven Mill. It’s been a long time so I’m coming back with a back to basics article. Hope you’ll enjoy.

The electricity smart meter is a device that measures electricity in the same way as the ordinary electricity meter but with the difference that it measures and stores much more data and parameters than the ordinary electricity meter.

Below you can see how one electricity smart meter for middle voltage looks like.
