摘要
用于贸易结算的电流互感器是强检计量器具.为保证互感器检定工作有序进行,标准器量值准确统一,内蒙古自治区市场监管局组织了区内的电流互感器量值比对.参加的实验室19家,均为已建标的法定计量技术机构,比对分为两组,采取环式比对方式.参考值的计算采用加权平均值法确定,各参比实验室归一化偏差小于1,比对结果满意.
Abstract
The current transformer used for trade settlement is a compulsory measuring instrument.In or-der to ensure the orderly progress of the calibration work for these transformers and the accurate and standardized values of the standard instruments,the Inner Mongolia Autonomous Region Market Supervi-sion Bureau organized a comparison of current transformer values within the region.Nineteen laboratories participated in the experiment,all of which are legally established metrological technical institutions.The comparison was divided into two groups,employing a loop-type comparison method.The calculation of the reference values was determined using the weighted average method.The normalized deviations of each reference laboratory were less than 1,and the comparison results were deemed satisfactory.
