标准摘要
[中文适用范围]： 仅适用于新制造的准确度等级为 2 级和 3 级的静态无功电表，用于测量 50 Hz 或 60 Hz 网络中的交流电无功电能，并且仅适用于其型式试验。出于实际原因，这 [外文原描述]： 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. This publication is of high relevance for Smart Grid .
