NEN-EN-IEC 62053-24 applies only to newly manufactured transformer operated static varhour 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 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. It applies only to static var-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 (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 also apply. It does not apply to: - var-hour meters where the voltage across the connection terminals exceeds 600 V (lineto- 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 standards of the IEC 62059 series.
