Since surface flashover of insulators in vacuum restricts the operation of the power equipment, improvement of surface flashover performance is of considerable importance in various fields. Previous studies show that surface flashover performance is closely related to the trap parameters of materials. In this paper, the crystallization behavior of low density polyethylene (LDPE) is modified by phenolphthalein...
To satisfy the rapid development of energy requirements, power transmission with higher voltage must be adopted. The large improvement in transmission voltage needs more excellent power equipment and better materials to meet its insulation requirement. PTFE nozzle used in high voltage circuit breaker faces the issue of arc ablation, and thus superior performance nozzles are urgently needed. In this...
ZnO varistors are used extensively as the surge suppressor in the form of surge arresters in the power protection against lightning, temporary over-voltages, switching surges, transients, etc. In this research, DC degradation process at 50 mA/cm2 for 115 hours and restorability by heat-treatment at 800 oC for 24 hours for ZnO varistors were performed. The breakdown field E1mA (electric field at 1...
CaCu3Ti4O12 is believed to have a variety of potential applications due to its unusual high dielectric constant and very high thermal stability. Ceramic films of CaCu3Ti4O12 differ from bulk specimens in dielectric and other physical properties. In this paper, the dielectric properties of CCTO thick films are investigated by SEM and dielectric spectra analysis. The difference thicknesses (0.1 mm,...
