数字式电能计量装置电量比对试验及误差分析

Comparision of Electric Energy Quantity Between Digital Electric Energy Measurement Devices and Error Analysis

针对数字式电能计量装置尚无检定标准的问题,进行数字式电能计量装置与传统电能计量装置电量比对试验,介绍试验原理、试验设备及条件、试验数据,分析电能综合误差测试方法和测试结果,并对2套电能计量装置计量的电量及综合误差的结果进行比对分析,结果表明数字式电能计量装置测量误差在合理范围内,可以用于电能计量。

Aiming at the problems digital electric energy measurement devices measurement standard,this paper introduces that test principle,test device and condition,test result of comparision between the digital electric energy measurement devices and traditional electric energy measurement devices,analyzes integrated error test method and test result,and compares the comparision result,validates the veracity of the digital electric energy measurement device.
