落实IEC标准变压器温度计全天候准确度规定的必要性研究

Necessity of Implementing the IEC Transformer Thermometer All-Weather Accuracy Requirements

针对变压器温度计国家标准准确度定义引发的变压器温度保护风险产生的原因进行了分析和计算,提出了通过采用IEC标准全天候准确度就可以排除计量失效、保护误动和两表偏差缺陷等风险。

This paper analyzes and calculates the causes of transformer temperature protection risk led by the definition of transformer thermometer national standard accuracy and proposes that the risks of measurement failure, protection misoperation and two-meter deviation can be eliminated by adopting IEC all-weather accuracy.
