Due to the excellent electrical properties, such as low dielectric loss, extremely low conductivity and high breakdown strength, polyimide film is widely applied as a kind of engineering plastic film and a type of insulating material in industry. However, with the disadvantage of organic polymer, its corona-resistance property is not good enough. During service operation, partial discharge (PD) may...
This paper presents a study on effects of flammation retardant in polycarbonate (PC) on the luminescence phenomena during the tracking tests. A photo multiplier tube was employed to measure the light intensity, which is found to be well in accordance with the development of tracking failure. The results obtained reveals that light is easily emitted when the phase angle of applied voltage is around...
