Review of Non-Destructive Testing Methods for Defects in Insulating Polymers
摘要
Abstract
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.
