New approaches to study environmental pollution effects on insulation of West Azarbayjan Electric Power Distribution Co

High voltage insulators are exposed to various climates. Pollution resources combined with moisture provide undesirable conductive paths on insulations that result in faults and economic losses. Types and degree specification of pollution seems to be vital for efficient operation and proper choice of insulation. Various climates, pollution resources like Oromieh Lake, cement and plaster factories, as well as industrial towns respect to localization necessity of international standards motivated authors to perform field and periodic pollution measurements in Azarabayjan province as a test place. The periodic measurements of ESDD-NSDD and DDG lead to the establishment of a pollution map of North-west of Iran. The different climatic parameters of Oromieh and Khoy are compared with pollution variation procedure of the test stations to assess climate influence on pollution accumulation. According to authors´ researches, we feel, proves that the ESDD measurement alone is not sufficient to establish the pollution severity level of a given site. Likewise, analysis of the site pollution severity and the weather data indicated a strong correlation of SPS with some of the climatic parameters. Thus, new approaches to study environmental pollution effects on insulation of West-Azarbayjan province are presented in this paper
