Insulation Characteristics and Evaluation Methods Under High Temperature and High Electric Field [Web Seminar]
With the spread of EVs, the driving voltage of motors is increasing, and miniaturization is progressing. Consequently, insulation materials for winding coatings must possess not only excellent heat resistance but also advanced insulation performance that can maintain stable operation under high voltage. Additionally, for SiC (silicon carbide) devices used in railways, industrial equipment, and power converters, selecting materials that can withstand harsh high-temperature and high-electric-field environments is urgently needed. Furthermore, similar performance is strongly required for insulation materials used in DC transmission cables that support the long-distance transport of renewable energy. However, there has not been a definitive method established for evaluating insulation properties under such high-temperature and high-electric-field conditions, which has hindered the formulation of guidelines for material development. This course will detail effective measurement methods based on years of research achievements for major polymer insulation materials such as polyimide, epoxy resin, and cross-linked polyethylene, and will introduce typical evaluation cases.
