    Abstract - (Show below) - (Hide below)

    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-to-line voltage for meters for polyphase systems); portable meters; reference meters. Methods for acceptance testing are covered by the IEC 62058 series of standards. The dependability aspect is covered by the documents of the IEC 62059 series.
