About this Research Topic
Insulating materials usually operate under high electrical stress, and also need to withstand mechanical stress and environmental stress (ultraviolet, high temperature, high humidity, etc.), and the degradation of their physical, chemical and electrical properties is inevitable. Accurate assessment of insulating material performance is essential for reliable operation, requiring advanced measurement methods that are precise, non-destructive, and capable of online testing. In recent years, advanced testing techniques such as dielectric response, ultrasonics, infrared thermography, microwave, terahertz, LIBS, and others have demonstrated significant potential in insulation material testing. These techniques have enabled non-destructive testing, online monitoring, and condition assessment of insulation materials to a certain extent. However, there are still problems such as unclear degradation mechanism of insulating materials, damaged detection methods, and unsatisfactory test accuracy for field applications. Therefore, in-depth research is needed to clarify the degradation mechanism of insulating materials and develop advanced performance testing technologies, ensuring the stable operation of power grid.
In this Research Topic, we call for papers focusing on the advanced testing technology for insulating material. We welcome researchers to contribute Original Research, Brief Research Reports and Review papers for this Research Topic. Potential topics include, but are not limited to:
• Deterioration mechanism of insulation material;
