IEC 62053-23-2016 pdf download.Electricity metering equipment (a.c.) – Particular requirements – Part 23: Static meters for reactive energy (classes 2 and 3).
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 networks 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 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 (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.
The safety aspect is covered by IEC 62052-31 :201 5.
