Furfural analysis of transformer oil
Furfural analysis of transformer oilFuran derivatives are a measure of the degradation of cellulose paper. When the paper ages, its degree of polymerization reduces, so its mechanical strength decreases. The degree of polymerization of the paper can be directly related to the concentration of furan derivatives ...
