Description of BS EN 50470-2:2006+A1:2018 2019

This European Standard applies to newly manufactured electromechanical watt-hour meters intended for residential, commercial and light industrial use, of class indexes A and B, for the measurement of alternating current electrical active energy in 50 Hz networks. It specifies particular requirements and type test methods.

It applies to electromechanical watt-hour meters for indoor and outdoor application, consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s).

If the meter has (a) measuring element(s) for more than one type of energy (multi-energy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces etc. are enclosed in the meter case (multi-function meters) then this standard applies only for the active energy metering part.

This standard distinguishes between:

  • meters of class indexes A and B;

  • direct connected and transformer operated meters;

  • meters for use in networks equipped with or without earth fault neutralizers.

It does not apply to:

  • watt-hour meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems);

  • portable meters.

A1_startThe safety aspect is covered by EN 62052‑31:2016.

Regarding acceptance tests see EN 62058‑11:20 and EN 62058‑21:20.A1_end
