Insulator pollution is one of the main problems with insulators on transmission lines and in substations. Utilities annually budget and allocate considerable resources for preventive and corrective maintenance to minimize system interruptions. Several methods are being used to predict the operative conditions of the insulation, such as the detection of visual corona on insulators, measurements of the equivalent salt deposit density (ESDD), and nonsoluble deposit density (NSDD), and measurement of the electric field along insulators [1] [4]. In Mexico, because of weak regulations, the pollution level has increased in recent years and the placement of heavy industries close to the overhead power system is a further cause of pollution. The use of nonceramic insulators is preferred by most of the utilities in Mexico; however, manufacturers do not recommend preventive maintenance.
