摘　　要：在对国内外非在线检测到在线检测微水的方法原理进行比较分析的基础上,分析了各种方法的优缺点,尤其对变压器油中微水检测总体方法进行了客观评价,指出目前在线检测准确度中存在的瓶颈问题.指出变压器油中微水检测方法的建立要考虑4个方面,即检测方法的复杂性、检测设备的灵敏性、检测结果的准确性以及检测方法及仪器推广的经济利益,并认为利用超声波进行检测是一种可行的新型检测方法.Based on the comparative analysis of methods and principles of monitoring moisture content between non-on-line and on-line in domestic and foreign countries, the author analyzed the good and bad points of each method, especially gave an objective evaluation of the overall method of monitoring moisture content in transformer oil and pointed out the bottleneck question of precision in on-line monitoring nowadays. There are four aspects of monitoring moisture content in transformer oil that need us to considerate： the complexity of monitoring methods, the sensitivity of monitoring equipment, the precision of monitoring results and the economic benefits of generalizing the monitoring methods and equipments. Finally, the author pointed out the method of using ultrasonic to monitoring moisture content is a new monitoring method.
