Porcelain and other Ceramic Insulating Materials [PDF]
Nature, 1944 THE pottery industry is almost virgin territory for the worker in applied science. Despite the trails blazed by J. W. Mellor in Great Britain and H. Seger in Germany, there are still wide tracts quite unexplored. There is still no institution of university status in Great Britain offering a full-time course in ceramics, and the number of qualified ...

Impact of Pollution Location on Time and Frequency Characteristics of Leakage Current of Porcelain Insulator String under Different Humidity and Contamination Severity [PDF]
Journal of Operation and Automation in Power Engineering, 2007 One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator
