摘要：In the field of power systems, insulating polymers have been found to have extensive applications due to their outstanding properties. However, these materials are susceptible to defects arising from various factors during production and operation, which may progress and potentially lead to safety incidents. This paper comprehensively reviews non-destructive testing (NDT) techniques for insulating polymers. Based on the physical principles underlying these methods, they are categorized into electrical testing methods, non-electrical passive testing methods, and non-electrical active testing methods. The paper offers a retrospective assessment of the applications of these methods in insulating polymers. Finally, evaluation of the applicability, advantages, and limitations of these diverse methods is systematically conducted, aiming to facilitate the targeted selection of the optimal NDT method in engineering applications.
