CENELEC - EN 50470-3

Electricity metering equipment (a.c.) Part 3: Particular requirements - Static meters for active energy (class indexes A, B and C)

active, Most Current
Organization: CENELEC
Publication Date: 1 October 2006
Status: active
Page Count: 36
ICS Code (Electricity supply systems): 91.140.50
scope:

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

It applies to static 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, B and C;

- 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-toline voltage for meters for polyphase systems);

- portable meters;

- reference meters.

The safety aspect is covered by EN 62052-31:2016.

Regarding acceptance tests see EN 62058-11:2010 and EN 62058-31:2010.

The dependability aspect is covered by the documents of the IEC 62059 series
