AS 62053.21:2018

Abstract

This Standard is an adoption with national modifications and has been reproduced from IEC 62053-21:2013 + A1:2016 CSV (ED.1.1), Electricity metering equipment (a.c.) – Particular requirements – Part 21: Static meters for active energy (classes 1 and 2). This Standard communicates to users, and also provides manufacturers with the particular requirements for class 1 and 2 active energy static meters intended for use in Australia.

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.
The safety aspect is covered by IEC 62052-31:2015.
Regarding acceptance tests, see IEC 62058-11:2008 and IEC 62058-31:2008.
The dependability aspect is covered by the standards of the IEC 62059 series.
