28、Electricity metering equipment (a.c.) Dependability Part 21: Collection of meter dependability data from the field This part is a standard for type testing electricity meters. It covers the particular requirements for meters, being used indoors. It does not deal with special implementations (such as

29、 metering-part and/or displays in separate housings). This standard is intended to be used in conjunction with IEC 62052-11. When any requirement in this standard concerns an item already covered in IEC 62052-11, the requirements of this standard take precedence over the requirements of IEC 62052-11

30、. This standard distinguishes: between accuracy class index 0,2 S and accuracy class index 0,5 S meters; between protective class I and protective class II meters; between meters for use in networks equipped with or without earth fault neutralizers. The test levels are regarded as minimum values tha

31、t provide for the proper functioning of the meter under normal working conditions. For special application, other test levels might be necessary and should be agreed on between the user and the manufacturer.

32、atic meters for active energy (classes 0,2 S and 0,5 S) 1 Scope This part of IEC 62053 applies only to newly manufactured static watt-hour meters of accuracy classes 0,2 S and 0,5 S, for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to thei

33、r type tests only. It applies only to transformer-operated static watt-hour meters for indoor 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 t

34、han 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 al

35、so apply. NOTE IEC 60044-1 describes transformers having a measuring range of 0,01 I n to 1,2 I n, or of 0,05 I n to 1,5 I n, or of 0,05 I n to 2 I n and transformers having a measuring range of 0,01 I n to 1,2 I n for accuracy classes 0,2 S and 0,5 S. As the measuring ranges of a meter and its asso

36、ciated transformers have to be matched and as only transformers of classes 0,2 S and 0,5 S have the accuracy required to operate the meters of this standard, the measuring range of the meter will be 0,01 I n to 1,2 I n. It does not apply to: watt-hour meters where the voltage across the connection t

37、erminals exceeds 600 V (line- to-line voltage for meters for polyphase systems); portable meters and meters for outdoor use; data interfaces to the register of the meter; reference meters. The dependability aspect is covered by the documents of the IEC 62059 series. 2 Normative references The follow

38、ing referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

41、2052-11 apply. 6 Climatic conditions The conditions given in IEC 62052-11 apply. 7 Electrical requirements In addition to the electrical requirements in IEC 62052-11, meters shall fulfil the following requirements. 7.1 Power consumption The power consumption in the voltage and current circuits shall

42、 be determined at reference conditions given in 8.5 by any suitable method. The overall maximum error of the measure- ment of the power consumption shall not exceed 5 %. The active and apparent power consumption taken at reference temperature and reference frequency, by each voltage circuit at refer

43、ence voltage and by each current circuit at rated current, shall not exceed the values shown in Table 1.

44、 circuit 1 VA 1 VA Auxiliary power supply 10 VA NOTE 1 In order to match voltage and current transformers to meters, the meter manufacturer should state whether the burden is inductive or capacitive. NOTE 2 The above figures are mean values. Switching power supplies with peak power values in excess

45、of these specified values are permitted, but it should be ensured that the rating of associated voltage transformers is adequate. NOTE 3 For multifunctional meters see IEC 62053-61. Page6 EN6205322:2003 7.2 Influence of short-time overcurrents Short-time overcurrents shall not damage the meter. The

46、meter shall perform correctly when back to its initial working condition and the variation of error at rated current and unity power factor shall not exceed 0,05 %. The test circuit shall be practically non-inductive and the test shall be performed for polyphase meters phase-by-phase. After the appl

47、ication of the short-time overcurrent with the voltage maintained at the terminals, the meter shall be allowed to return to the initial temperature with the voltage circuit(s) energized (about 1 h). The meter shall be able to carry for 0,5 s a current equal to 20 I maxwith a relative tolerance of +0

48、 % to 10 %. 7.3 Influence of self-heating The variation of error due to self-heating shall not exceed the values given in Table 2.

The meter error shall be measured at unity power factor immediately after the current is applied and then at interva
