    Abstract - (Show below) - (Hide below)

    Specifies safety and performance requirements for general purpose single-rate and multi-rate induction watthour meters with terminals arranged for the bottom connection or with contact blades arranged for the meter to plug-in to a socket conforming to AS 1284.4. Supersedes requirements for two-rate meters previously specified in AS 1284.3 - 1973.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for general purpose single-rate and multi-rate induction watthour meters (hereinafter referred to as 'meters') for the measurement of 50 Hz a.c. electrical energy in domestic, industrial or commercial premises.The Standard specifies terminal arrangements and connections for bottom-connected meters, also contact blade arrangements and connections for single-element single-phase 2-wire plug-in meters by cross-reference to AS 1284.4.For transformer-operated meters, the standard specifies secondary registration (see Clause 2.8.1.2) and the applicability of an appropriate transformer ratio constant.NOTES:1. For voltage transformers and current transformers, see AS 1243 and AS 1675 respectively.2. In order to facilitate the specification and purchase of meters, the Standard lists information which should be supplied with enquiry and order (see Appendix A).
