Regarding supported standard

Category: Datasheet/Specs
Product Number: ADE7953

In the datasheet of the IC ADE7953, it is mentioned that it supports the industry standards mentioned below:

EN 50470-1, EN 50470-3, IEC 62053- 21, IEC 62053-21, IEC 62053-22, and IEC 62053-23 standards.

What does it exactly mean with respect to the data being read by the aforementioned IC?

  • This means that any measurements we provide in the ADE7953 have been designed to meet the definition of the measurement in that standard. For instance how active power is defined. 


  • Dear Dave,

    Thanks for your prompt reply.

    Could you elaborate a bit more on this please?

    Thanks and regards


  • For example in the datasheet we have the definition of RMS 

     We implement the RMS below 

    All the standards listed are different metering standards that have a lot of information not all is relevant for the ADE7953 but when it comes to calculations of active power reactive power and RMS we meet the standard for total Watt and total VAr. and total RMS

    Reactive power can be defined as total reactive and fundamental reactive. The ADE7953 is total reactive power. ADE7878 has fundamental and total VAR WATT VA and Fundamental RMS 

    It is up to the user to determine if the measured quantity from the ADE7953 specific standard 

    I have listed the standards and the titles below and some text from the standards showing EN standards point to IEC standards. 

    The important thing is you supply a given set of signals based on the standard (V I and PF) and the standard expects a certain result. There are many ways of calculating quantities in the standard and they will all give outputs that meet the standard. 

    "62053-22, Ed.1: Electricity metering equipment (AC) - Particular requirements -
    Part 22: Static meters for active energy (classes 0,2 S and 0,5 S)"

    IEC 62053-21 Static meters for active energy (classes 1 and 2)

    iec62053-23 Static meters for a.c. reactive energy (classes 2 and 3)

    This EN 50470-3 is related to:
    – EN 62053-21:2003, Electricity metering equipment (a.c.) – Particular requirements –
    Part 21: Static meters for active energy (classes 1 and 2) and
    – EN 62053-22:2003, Electricity metering equipment (a.c.) – Particular requirements –
    Part 22: Static meters for active energy (classes 0,2 S and 0,5 S).

    This EN 50470-1 is related to EN 62052-11:2003, Electricity metering equipment (a.c.) – General
    requirements, tests and test conditions – Part 11: Metering equipment.
    The structure of the two standards is similar, modifications in this European Standard are provided in
    the perspective of compliance with the essential requirements of the Directive 2004/22/EC on
    Measuring Instruments (MID).
    This standard is to be used with:
    – EN 50470-2:2006, Electricity metering equipment (a.c.) – Part 2: Particular requirements –
    Electromechanical meters for active energy (class indexes A and B) or
    – EN 50470-3:2006, Electricity metering equipment (a.c.) – Part 3: Particular requirements –
    Static meters for active energy (class indexes A, B and C).
    This European Standard has been prepared under a mandate given to CENELEC by the European
    Commission and the European Free Trade Association and covers essential requirements of EC
    Directives 89/336/EMC and 2004/22/EC. See Annex ZZ.

    You need to understand the meter market you are targeting and the metering quantities you need to meet.
