Organization: IEC
Publication Date: 1 January 2003
Status: inactive
Page Count: 54
ICS Code (Measurement of electrical and magnetic quantities): 17.220.20
scope:

This part of IEC 62053 applies only to newly manufactured static watt-hour meters of accuracy classes 1 and 2, for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only.

It applies only 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 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, then the relevant standards for these elements also apply.

It does not apply to:

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

- portable meters;

- data interfaces to the register of the meter;

- reference meters.

Regarding acceptance tests, a basic guideline is given in IEC 61358.

The dependability aspect is covered by the standards of the IEC 62059 series.
