Resumo

SALVADOR, BRAZIL, METROPOLITAN REGION.The performances of eight kinds of insulators from electrical distribution lines in Salvador-BA, Brazil, were evaluated considering the chemical and physical local environmental pollution.The parameters that were chosen as characteristic for the insulators' properties were leakage current and partial electrical discharge.A data storage processing system and a communication link to the lab were built for data acquisition.The results show that the main contribution to the poor performance of the insulators is settleable magnetite particulate matter on the insulator in addition to the long term wetness time, t 4 .
