Non Linear Regression Model to Predict Flashover of Nonceramic Insulators

This work is based on the application of non-linear regression analysis technique to develop a model for prediction of flashover voltage of non-ceramic insulators (NCIs). The superiority of nonlinear model over a linear model is demonstrated. Surface resistance measurement and flashover experiments were performed with field aged samples. This work finds applications in distribution class insulators and can be extended for higher voltage class of insulators.
