BS EN IEC 62053-24:2021+A11:2021 PDF

Scope: 1 Scope This part of IEC 62053 applies only to static var-hour meters of accuracy classes 0,5 S, 1 S, 1, 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. This document 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 IEC 62053‑23, where reactive power and energy is only defined for sinusoidal signals. In this document 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 definition, reactive power and energy reflects the generally unnecessary current possible to compensate with capacitors rather than the total unnecessary current. NOTE 2 For other general requirements, such as safety, dependability, etc., see the relevant IEC 62052 or IEC 62059 standards. 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; ...
