摘要
JJF1619-2017《互感器二次压降及负荷测试仪校准规范》中规定了互感器二次压降及负荷测试仪校准工作的原理、方法、项目及要求等,是技术人员实验室校准工作的主要依据,但对于二次压降校准点没有具体规定,只提出了原则性要求。笔者根据多年来现场实际测试的二次压降大数据和实验室校准工作中遇到的各种问题,提出了二次压降校准点设置的见解供广大从事互感器二次压降及负荷测试校准工作的技术员参考。
JJF1619-2017《Calibration Specification for Testing Instrument of Transformer Secondary Loop Voltage Drops and Loads》specifies principle,methods,items and requirements for testing work of transformer secondary loop voltage drops and loads.It is the main basis of laboratory calibration for technicians.There is no specified stipulations but principle requirements for calibrated points.Based on the big data of secondary loop voltage drops from field test and various problems encountered in laboratory calibration work over the years,the idea of setting calibration points of secondary loop voltage drops is put forward for the reference of technicians engaging in testing work of transformer secondary loop voltage drops and loads.
