当测量温度中使用电阻式温度检测器，励磁电流本身这个温度产生I 2r，或焦耳热化，产生一个比指示温度稍微高一点的温度标准。
When measuring temperature using an RTD, the excitation current itself produces I 2r, or Joule heating, producing an indicated temperature somewhat higher than the temperature being measured.
介绍了电流比是小数的电流互感器的检定，以及电流比例标准的灵活应用及检测时给被检电流互感器带来的附加误差。
This paper introduces the calibration of current transformers with special current ratio of decimal fraction the application of the current comparator is also introduced.
