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 and outdoors. It does

30、 not deal with special implementations (such as 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 p

31、recedence over the requirements of IEC 62052-11. This standard distinguishes: between accuracy class index 2 and accuracy class index 3 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 le

32、vels are regarded as minimum values that 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. Page4 EN6205323:2003 ELECTRICITY METERING EQUIPMENT (

33、AC) PARTICULAR REQUIREMENTS Part 23: Static meters for reactive energy (classes 2 and 3) 1 Scope This part of IEC 62053 applies only to newly manufactured static var-hour meters of accuracy classes 2 and 3, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz netwo

34、rks and it applies to their type tests only. For practical reasons, this standard is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only. It applies only to static var-hour meters for indoor and outdoor application cons

35、isting 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 indicator

36、s, 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: var-hour meters where the voltage across the connection terminals exceeds 600

37、V (line- to-line voltage for meters for polyphase systems); portable meters; 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 following referenced documents are indispensable for t

44、 and 10 VA 0,5 VA Auxiliary power supply 10 VA NOTE 1 In order to match voltage transformers to meters, the meter manufacturer should state whether the burden is inductive or capacitive (for transformer operated meters only). NOTE 2 The above figures are mean values. Switching power supplies with pe

45、ak values in excess 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. 7.1.2 Current circuits The apparent power taken by each current circuit of a direct connected met

46、er at basic current, reference frequency and reference temperature shall not exceed the values shown in Table 2. The apparent power taken by each current circuit of a meter connected through a current transformer shall not exceed the value shown in Table 2, at a current value that equals the rated s

The meter shall perform correctly when back to its initial working condition and the variation of error shall not exceed the values shown in Table 3. The test circuit shall
