计量误差(metering error) 指电能计量装置(如电表)测量结果与被测量真值之间的偏差。在电力系统中,它直接关系到贸易结算的公平性与电网监测的准确性,其核心构成包括:
定义与分类
行业标准与限值
国际电工委员会(IEC)和IEEE标准规定:
主要影响因素
权威参考来源:
metering error 是由两个核心概念组成的专业术语:
metering(计量/测量)
error(误差/错误)
组合含义
metering error 指在计量或测量过程中产生的误差,属于技术领域的常见术语。例如:
相关术语可参考:gas metering(燃气计量)、exposure metering(测光模式)。
