This Standard is an adoption with national modifications and has been reproduced from IEC 62053-24:2016+AMD.1:2016 CSV (ED.1.1), 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). This Standard communicates to users, and also provides manufacturers, with the particular requirements for class 1 and 0.5 reactive energy static meters intended for use in Australia.

This part of IEC 62053 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.
