28、the field This part is a standard for type testing electricity meters. It covers the particular requirements for meters, being used indoors and outdoors in large quantities world-wide. It does not deal with special implementations (such as metering-part and/or displays in separate housings). This st

29、andard 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. This standard distinguishes: between accuracy class index 0

30、,5, accuracy class index 1 and accuracy class index 2 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 that provide for the proper functioning of the

31、 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 EN6205311:2003 ELECTRICITY METERING EQUIPMENT (AC) PARTICULAR REQUIREMENTS Part 11: Electromechanical meters for active energy (c

32、lasses 0,5, 1 and 2) 1 Scope This part of IEC 62053 applies only to newly manufactured electromechanical watt-hour meters of accuracy classes 0,5, 1 and 2, for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. It appli

33、es only to electromechanical watt-hour meters for indoor and outdoor 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 than one type of energy (m

34、ulti-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 also apply. It does not app

35、ly to: watt-hour meters where the voltage across the connection terminals exceeds 600 V (line- to-line voltage for meters for polyphase systems); portable meters; data interfaces to the register of the meter. Regarding acceptance tests, a basic guideline is given in IEC 60514. The dependability aspe

36、ct is covered by the documents of the IEC 62059 series. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inclu

37、ding any amendments) applies. IEC 60514:1975, Acceptance inspection of Class 2 alternating-current watt-hour meters IEC 60736:1982, Testing equipment for electrical energy meters IEC 62052-11:2003, Electricity metering equipment (a.c.) General requirements, tests and test conditions Part 11: Meterin

38、g equipment 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 62052-11 apply. Page5 EN6205311:2003 4 Standard electrical values The values given in IEC 62052-11 apply. 5 Mechanical requirements In addition to the mechanical requirements in IEC 62052-11

39、, electromechanical meters shall fullfil the following requirements. 5.1 General The case of an electromechanical watt-hour meter shall be so constructed that, if mounted according to the manufacturers instructions, the meter shall not deviate by more than 0,5 in all directions from its vertical pos

40、ition (see also note 2 of Table 11). 5.2 Register (counting mechanism) The register may be of the drum or the pointer type. In drum-type registers, the principal unit in which the register records shall be marked adjacent to the set of drums. In this type of register, only the last drum, i.e. the dr

41、um on the extreme right, may be continuously movable. In pointer-type registers, the unit in which the register records shall be marked adjacent to the units dial in the form: 1 kWh/div, or 1 MWh/div, and the decimal multiples may be marked adjacent to the other dials. For example, in a meter regist

42、ering in terms of kilowatthours, the units dial shall be marked: 1 kWh/div and, adjacent to the other dials to the left of the units dial, shall be marked: 10 100 1 000, etc. 5.3 Direction of rotation and marking of the rotor The edge of the rotor nearest to an observer viewing a meter from the fron

43、t shall move from left to right for positive registration. The direction of rotation shall be marked by a clearly visible arrow. The edge and/or upper surface of the disk shall carry an easily visible mark to facilitate revolution counting. Other marks may be added for stroboscopic or other tests, b

44、ut such marks shall be so placed as not to interfere with the use of the main visible mark for photoelectric revolution counting. 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 fulfi

45、l the following requirements. 7.1 Power consumption The power consumption in the voltage and current circuit shall be determined at reference conditions given in 8.5 by any suitable method. The overall maximum error of the measurement of the power consumption shall not exceed 5 %. Page6 EN6205311:20

46、03 7.1.1 Voltage circuits The active and apparent power consumption in each voltage circuit of a meter at reference voltage, reference temperature and reference frequency shall not exceed the values shown in Table 1. Table 1 Power consumption in voltage circuits Class of meter Meters 0,5 and 1 2 Sin

47、gle-phase and polyphase 3 W and 12 VA 2 W and 10 VA NOTE 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). 7.1.2 Current circuits The apparent power taken by each current circuit

48、 of a direct connected meter 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 valu

49、e that equals the rated secondary current of the corresponding transformer, at reference temperature and reference frequency of the meter.
