It covers the par

38、ticular requirements for meters, used indoors and outdoors. It does 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 alread

39、y covered in IEC 62052-11, the requirements of this standard take precedence over the requirements of IEC 62052-11. This standard distinguishes: between transformer operated meters of accuracy class index 0,5 S and 1 S and direct connected meters of accuracy class index 1; between protective class I

40、 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 meter under normal working conditions. For special application, other test levels might

41、 be necessary and should be agreed on between the user and the manufacturer. BS EN 62053-24:2015IEC 62053-24:2014 IEC 2014 7 ELECTRICITY METERING EQUIPMENT (a.c.) PARTICULAR REQUIREMENTS Part 24: Static meters for reactive energy at fundamental frequency (classes 0,5 S, 1 S and 1) 1 Scope This part

42、of IEC 62053 applies only to newly manufactured transformer operated static var-hour meters of accuracy classes 0,5 S, and 1 S as well as direct connected static var-hour meters of accuracy class 1, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and

43、it applies to their type tests only. This standard uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the currents and voltages only. See Clause 3. NOTE 1 This differs from the approach of IEC 62053-23, whe

44、re reactive power and energy is defined only for sinusoidal signals. In this standard reactive power and energy is defined for all periodic signals. Reactive power and energy is defined in this way to achieve proper reproducibility of measurements with meters of different designs. With this definiti

45、on, reactive power and energy reflects the generally unnecessary current possible to compensate with capacitors rather than the total unnecessary current. It applies only to static var-hour meters for indoor and outdoor application consisting of a measuring element and register(s) enclosed together

46、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 indicators, electronic tariff registers, time switches, ripple control re

47、ceivers, data communication interfaces, etc., are enclosed in the meter case, then the relevant standards for these elements also apply. NOTE 2 IEC 61869-2:2012 describes transformers having a measuring range of 0,05 Into Imaxfor accuracy classes 0,2, 0,5, 1 and 2, and transformers having a measurin

48、g range of 0,01 Into Imaxfor accuracy classes 0,2 S and 0,5 S. As the measuring range of a meter and its associated transformers have to be matched and as only transformers of classes 0,2 S / 0,5 S have the current error and phase displacement characteristics suitable to operate a class 0,5 S / 1 S

49、meter respectively as specified in this standard, the measuring range of the transformer operated meters will be 0,01 Into Imax. Reactive meters intended to be used together with non-S transformers are, therefore, not covered by this standard. It does not apply to: var-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
