1 Scope

This document stipulates that for newly manufactured devices that measure AC reactive power in a 50Hz or 60Hz power grid, the accuracy level is 0.5S, Type test requirements and test methods for static reactive energy meters (hereinafter referred to as "meters") of class 1S, class 1, class 2 and class 3. This document uses the traditional definition of reactive energy, where reactive power and reactive energy are calculated from only the fundamental frequency components of current and voltage (See Chapter 3). Note 1.Unlike GB/T 17215.323, which is only applicable to sinusoidal signal occasions, the definition of reactive power and reactive energy is different. In this document, reactive power and reactive energy The functional energy definition applies to all periodic signals. The reactive power and reactive energy defined by this method can make the instruments of different designs obtain suitable appropriate measurement reproducibility. According to this definition, reactive power and reactive energy reflect the vast majority of reactive currents that can be compensated by capacitors, while Not all reactive current. Note 2.Other general requirements for instruments, such as safety, reliability, etc., see GB/T 17215.231 and GB/T 17215.9 (all parts). This document applies to the following electrical energy measuring equipment. ---Measure and control the reactive energy in the power grid (power supply) with an AC voltage of 600V or below; Note 3.For AC watt-hour meters, the above-mentioned voltage is the voltage of the line-to-neutral line derived from the nominal voltage, see Table 7 of GB/T 17215.231-2021. --- Except for the indicator display, all functional units, including additional modules, are encapsulated in a watch case or form a separate watch case; --- Use an integrated or separate indicator display, or not use an indicator display; ---Installed on the specified supporting socket or rack; ---It can choose to provide other functions besides electric energy measurement. Instruments designed for use with low-power instrument transformers (LPIT, defined in the GB/T 20840 series of standards) are only available in These instruments are considered to comply with this document when they are tested together with their LPIT and meet the requirements for direct access instruments. Note 4.Modern watt-hour meters usually include additional functions, such as the measurement functions of voltage amplitude, current amplitude, power, frequency, power factor, etc.; The function of quantity; the control function of load; the function of transmission, timing, test, settlement and recording; the function of data communication interface and related data security. delete this document Relevant standards may apply to these functional requirements.
