Research Status of Experimental Characterization of Materials Electrical Properties

Abstract

With the continuous development of the power industry, the electrical properties of materials are required to be higher. In the process of material research and development, accurate characterization of electrical insulation properties is the focus of experts and scholars. The most basic electrical performance and its characterization indexes include: electrical strength is the commonly used characterization index of electrical breakdown characteristics, resistivity is the commonly used characterization index of electrical conduction characteristics, and relative dielectric constant and dielectric dissipation factor are the commonly used characterization indexes of dielectric properties. In view of the above three kinds of indexes, this paper summarizes the principles and influencing factors involved in the experimental characterization of electrical properties of materials, traditional measurement methods, and new progress in experimental characterization.
