Electricity metering equipment - Particular requirements - Part 23: Static meters for reactive energy (classes 2 and 3)
IEC 62053-23:2020 applies only to 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 document is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC; • have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays; • operate with integrated or detached indicating displays, or without an indicating display; • be installed in a specified matching socket or rack; • optionally, provide additional functions other than those for measurement of electrical energy. Meters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series) may be considered
