This part is the first part of JB/T5467, based on GB/T15283-1994 "0.5, 1 and 2 Class AC Active Watt-hour Meter" (EC521:1988Class0.5 , land2alternating current watt-hourmeters) and GB/T15282-1994 "Reactive energy meters" (IEC145:1963Reactive energymeters)
The main differences between this part and GB/T15283-1994 and GB/T15282-1994 are as follows: increase The classification of electric energy meters was stipulated, and the environmental conditions for the use of electric energy meters were stipulated: the requirements for reliability of electric energy meters were added: the inspection was divided into type inspection, periodic inspection and factory inspection, and the corresponding inspection items were listed: The requirements and test methods are written separately, and test methods, inspection rules and packaging and storage regulations are added: 1. Refer to IEC62052-11/CDV "Electric Energy Measuring Equipment (ac) - General Requirements, Test and Test Conditions - Part 11: Measurement According to the regulations of "Equipment", mechanical performance tests are added, including impact test, vibration test, dustproof and waterproof test: referring to the regulations of EC62052-11/CDV, dry heat, low temperature, alternating damp heat test and sunlight resistance test are added Regulations: - With reference to the regulations of C62052-11/CDV, electric energy meters are divided into two categories: those connected directly and those connected through transformers. The requirements are stipulated respectively: - Refer to C62053-11/CDV "Electric Energy Measuring Equipment (ac)" ) - Special Requirements - Part 11: Electromechanical Active Energy Meters (0.51 and 2 Levels)" regulations, adding requirements and test methods for the effects of voltage imbalance: refer to the regulations of EC62052-11/CDV, for on-band ground faults The electric energy meter used in the power grid of the balancer has added requirements for ground fault resistance:
Referring to the regulations of EC62052-11/CDV, the electric energy meter is classified into Class 1 and Class II enclosed electric energy according to insulation protection. Table, supplemented with the regulations on clearance and creepage distance of Class 1 and Class II protective insulation-encapsulated energy meters: 1. Refer to C610361 and Class 12 Stationary AC Active Energy Meters and EC60687 "AC Static Active Energy Meters (0.25 and 0.5S level)" standard stipulates the time for starting and creeping tests. This part is a revision of the standard JB/T54671997 AC Active and Reactive Energy Meters. Compared with JB/T5467-1997, in addition to the above differences, this part also has the following differences: a) Use environmental conditions refer to C62052-11 /CDV file, divided into indoor type (Group P) and outdoor type (Group C) electric energy meters: b) The test methods of the new entries are supplemented accordingly, and all test methods are improved as much as possible to enhance the reliability of the test methods. Appendices A and B of the original standard have been revised accordingly, and appendices C, D and E have been added. Appendix B (informative appendix) gives the appearance dimensions and installation dimensions of the electric energy c
meter, in an effort to gradually unify the appearance and installation dimensions of the electric energy meter. This part replaces JB/T5467-1997 AC active and reactive energy meters. Appendix A, Appendix C, Appendix D and Appendix E of this part are normative appendices, and Appendix B is an informative appendix. This part is proposed by China Machinery Industry Federation.

JB/T5467.1—2002
JB/T5467.1 "Electromechanical AC active and reactive energy meters Part 1: General requirements" is JB/T5467 -Revision of the 1997 "AC Active and Reactive Energy Meters" standard. The revision of the standard was to make the standard structure compatible with the special requirements of long-life electric energy meters, so the basic content of the original JB/T5467-1997 standard was revised as Part 1, becoming an electromechanical AC active and reactive energy meter. The general requirements for long-life electric energy meters are included as part 2 of the standard; on the other hand, the International Electrotechnical Commission has recently made adjustments to the structure and performance of the standard: the entire electric energy metering equipment has been included in the standard. In the C62052 and C62053 series of standards, electromechanical and static electric energy meters are completely unified in terms of use conditions, which is consistent with the aspirations of the domestic electric energy meter industry. This revised part fully embodies the above spirit
This part is marked with GB /T15283-1994 (0.5, 1 and 2 level AC active watt-hour meter\ (equivalent to EC521-1988) and GB/T15282-1994 "Reactive watt-hour meter" (equivalent to EC145-1963), and fully Taking into account EC62052-11/CDV "Electrical energy measuring equipment (ac) - General requirements, tests and test conditions - Part 11: Measuring equipment" and C62053-11/CDV "Electrical energy measuring equipment (ac) - Part 11 special requirements" : Electromechanical Active Energy Meter (Level 0.5, 1 and 2)" document is a revision of the original standard. This standard is a domestic trade and quality supervision standard. Since the positive C standard is the same as the GB/T15283-1994 "0.5, 1 and 2-level AC active energy meter" standard and the GB/T15282-1994 "Reactive energy meter" standard, they are only applicable to the type inspection of the latest manufactured energy meters. : There are no provisions for routine inspection and periodic inspection items, and the arrangement and writing of the standards are different from the writing habits of domestic standards; furthermore, these standards do not make provisions in terms of reliability, etc., and these provisions have a negative impact on the current domestic production The electric energy meter used is required. Therefore, this part is the same as the B/T5467~1997 standard. It is a supplement and improvement to GBT15283-1994 and GB/T15282-1994. The electric energy meters sold in China shall undergo factory inspection and inspection according to the requirements of this part. Quality assessment is conducted to meet the needs of domestic production and trade and ensure that products produced in accordance with this section have high technical indicators and strong market competitiveness.

The electric energy meter connected by transformer refers to the electric energy meter connected by fixed ratio transformer. The electric energy meter can directly read the watt-hours (or kilovar-hours) of the recorded electric energy: for the electric energy meter connected by multi-purpose transformer, the reading of the electric energy meter needs to be multiplied by the change of the transformer. 4.1.2 Classification by grade index

4.1.3 Classification by ability to withstand environmental conditions
Electric energy meters are classified into two types according to their ability to withstand environmental conditions: Group P (indoor electric energy meter) and Group C (outdoor electric energy meter). The basic environmental conditions of each group of electric energy meters are shown in Table 1.
