This standard is the first revision of GB/T15284-1994. GB/T15284—2002
This revision directly refers to the requirements of GB/T17215—2002 "Class 1 and Class 2 Static AC Active Watt-hour Meters" (idtIEC61036:2000) in terms of "standardized electrical quantity values, mechanical requirements, climatic conditions, electromagnetic compatibility (EMC) and test methods". The "special requirements" of the measuring unit should comply with the relevant electric energy meter standards. This standard only stipulates the special requirements of multi-rate electric energy meters to facilitate coordination between standards.
IEC/TC13 will re-arrange the numbers of the current standard documents in layers to standardize the standard system and facilitate coordination between standards. The requirements for electric energy meter products are included in IEC62052-11 "General test and test conditions for electric energy measuring equipment (ac,) Part 11: Measuring equipment", while the special requirements of the products are included in IEC62053 "Special requirements for electric energy measuring equipment (ac)" and formulated according to specific equipment. This standard follows this principle. The writing format of this standard adopts the provisions of GB/T1.1-2000 "Guidelines for standardization work Part 1: Structure and writing rules of standards". This standard replaces GB/T15284-1991 "Multi-rate (separate attachment) electric energy meter". The main changes of this standard compared with GB/T -15284-1994 are as follows: the name of the standard is changed to "Special requirements for multi-rate electric energy meters"; the table of contents is supplemented; the latest version of normative documents is quoted. - Added "Functional requirements\ (see 5.1): Anti-ground fault (ability), conducted disturbance induced by radio frequency field, surge voltage, radio interference suppression requirements (see 5.4.9, 5.5): Added "output device" (see 5.7.6.7) "Product instruction manual" (see 8.2).
