摘要(Abstract):
针对标准电能表检定装置在小电流(10 m A及以下)工况下的检定准确度,用实验室现有的2套装置与型号为MTS320的装置进行数据对比,分析原因,并采用简易峰—峰值的方法对装置进行输出功率稳定度评定,发现MTS320能准确测试出被试品的基本误差,更能适应IR46电能表国际建议的要求。
According to the accuracy of electric energy meter verification equipment under small current(10 m A and below) output, data comparison is conducted among two existing laboratory equipment and MTS 320 equipment, and the reasons are analyzed. Simple peak-to-peak value is used for output power stability assessment of the device, and it is found that MTS 320 can accurately obtain the basic error of the tested equipment and accommodate international suggestions on IR46 electric energy meter.
