Abstract

This paper developed a simple linear regression model to predict the flashover voltage of polluted porcelain insulators based on Equivalent Salt Deposit Density (ESDD). The developed model Y = 58.75 – 63.69(ESDD) demonstrated strong predictive capability, with a correlation coefficient (R) of 95.28%, indicating near-perfect alignment between predicted and experimental values. An R² value of 90.78%, confirming that ESDD explains most of the variability in flashover voltage. Statistically significant results (p-value (0.0471), F-statistic (19.70)), validating the model’s reliability. It is simple yet accurate predictive model bridging the gap between laboratory experiments and field applications in pollution flashover analysis. This analysis demonstrates that ESDD is a critical predictor of flashover.
