Abstract
The prevailing method based upon the oil-paper balance curve for evaluating the moisture content in transformer pressboard is faced with serval limitations. Therefore, the aim of this paper is to report an available approach to accurate predict the moisture content of pressboard. The published researches reveal that there exists an obvious variation law between moisture content and relevant dielectric response characteristic parameter. Consequently, the variation law between moisture content and the integral value of dielectric loss factor is studied in this work. Further, the functional relationship between integral value and moisture content is established by fitting analysis. Finally, the purpose of quantitative evaluation of moisture content is realized.
