Resistance Measurements and Interpretations Relating to Flashover of Artificially Contaminated Ceramic Insulator Strings

, 2003
The flashover of insulator strings occurring at normal working voltages under contaminated/polluted conditions obviously deserves serious consideration. Though much research has been gone into pollution-induced flashover phenomena, grey areas still exist
