Abstract: According to the requirements of chapter 14.1 of the new GB/T 19212.1-2016 standard implemented on March 1, 2017, and combined with small transformer products, the method of measuring the temperature rise of winding resistance by resistance method is analyzed. According to the experience of many years' testing and operation ability verification project, the temperature rise of winding resistance measured by resistance method is explained in detail through enumerating cases. Key steps and influencing factors.
