Abstract: 

POLLUTION DEPOSIT ON ELECTRIC INSULATION SYSTEM OF T&D NETWORKS IN SOUTH PART IF IRAN NEAR THE COAST OF PERSIAN GOLF AND OMAN SEA IS THE MAJOR REASON OF INSULATION FAULTS IN THESE AREAS. SEVERITY OF DESERT-COASTAL POLLUTION LEVEL AND SEVERE CLIMATIC CONDITION I.E. LONG DRY PERIOD ,HIGH DEGREE OF THERMAL-HUMIDITY COMBINATION ,SEA-BORN WIND BLOWING AND FREQUENT DEW FORMATION DURING THE YEAR, MAKE THE POLLUTION LAYER OF INSULATORS WET. THIS PHENOMENA WITH FORMING A CONDUCTIVE ROUTE CAUSES PASSING THE LEAKAGE CURRENT WHICH WILL LEAD TO THE FLASHOVER OCCURRENCE FINALLY.
BY DETERMINATION OF MAXIMUM POLLUTION SEVERITY ON INSULATION SYSTEMS IN 20 TEST STATION WHICH INSTALLED IN DIFFERENT PARTS OF HORMOZGAN PROVINCE AND WITH ANALYZING THE ADAPTABILITY OF TEST RESULT WITH ENVIRONMENTAL PARAMETERS VARIATION INCLUDING DRY PERIOD LENGTH ,MAX. TEMPERATURE ,RELATIVE HUMIDITY, NO. OF DAYS WITH SAND STORM, NO. OF DAYS WITH HAZE ,VAPOR PRESSURE AND DOMINATED WIND DIRECTION OF REGION IT WAS FOUND OUT THAT THERE WOULD BE A CORRELATION BETWEEN THE RATE OF POLLUTION DEPOSIT, ENVIRONMENTAL PARAMETERS VARIATION AND FAULT NUMBERS WHICH CAN BE SIMULATED BY STATISTICAL ANALYSIS AND NEURAL SYSTEMS. THE LOCAL EXPLOITATION EXPERIENCE AND FAULT ANALYSIS CONFIRM THIS PHENOMENA. IN THIS PAPER THE RESULT OF RESEARCH AND DISCUSSION REGARD TO ABOVE MENTIONED CONCEPTS, HAS BEEN PRESENTED.
