Dynamic simulation of risk of flashover of contaminated ceramic insulators

A computer model is developed which dynamically sim~tlatet~he risk of jlashover oj contaminated insulators under real time change of the climatic environmental factors From data oj accumulation of contaminant, cleaning by ruin, wetting by moiJture, risk of jhhover of a ceramic insulator is calculated which then gives the resultant risk ojjlashover of a system where several hundred number of ceramic insulators connected in parallel are Jubjected to the Jame degree of contamination Jeverity and wetting
