The magnetic testing methods on Fe-based amorphous alloy strips are summarized , mainly involved for the power frequency magnetic testing methods on the Fe-based amorphous alloy used in distribution transformer, including ring specimens method and single sheet method. The methods to select the corresponding testing technology for different samples and different test requirements are put forward by introducting the principle, application status, applicability and the existing problems and analyzing the differences between measuring results of the two kinds of detection technology.
