单相电度表简易现场校验法

Simple and Easy Methods of Testing a Single-phase Kilowatt-hour Meter in Worksite

对单相电度表的接线进行了分析,阐述了错误接线时产生负误差的主要原因。针对在农村、乡镇中单相电度表受检率低、完好准确率低的情况,介绍了两种有负载、电度表转动,而转速不准确时的简易现场校验方法,并对其误差来源做了分析。

In this article first we study on the wiring of a single-phase kilowatt-hour meter, and analyse how the negative errors are produced when it is under a wrong mode.Then being directed against the fact that single-phase kilowatt-hour meters in countryside are tested with a lower proportion and they are with a lower qualified proportion, we present two simple and easy methods to test a single-phase kilowatt-hour meter in worksite, and analyse the sourse of the errors in each method.
