摘要
通过现场测试油纸电容式套管介质损耗因数的实例,针对测试中出现的误差进行了分析、探讨,得出了因相对湿度偏高而产生的表面泄漏电流是引起套管介质损耗因数测试误差的主要原因,并提出具体处理方法。
An example of on-line tanδ measurement of an oil paper capacitive bushing is introduced, and the measurement error is analyzed. By analyzing the cause of the error, the surface leakage current due to higher relative humidity is found the key reason for causing the measurement error of tanδ, and the countermeasure is provided.
