Abstract
A new approach is presented to predict the flashover of EPDM (ethylene propylene diene monomer) NCI (nonceramic insulators) in service based on the measurement of surface resistance in the laboratory. This method is shown to be more accurate in predicting flashover of NCI when compared to conventional ESDD (equivalent salt deposit density) measurement. A critical value of surface resistance that will result in a flashover has been determined which is useful for assessing the condition of in-service NCI with respect to flashover.
