Performance of hv transmission line insulators in desert conditions part III. Pollution measurements at a coastal site in the eastern region of saudi arabia

Contamination flashover is the major cause of insulator failure in the eastern region of Saudi Arabia. Saudi Consolidated Electric Company in the eastern region (SCECO East) has adopted several countermeasures such as increasing the creepage distance and using insulators of different shapes and materials including resistive-glazed insulators. The utility, however, still relies primarily on an expensive, rigorous maintenance program.
