Abstract

THIS PAPER PRESENTS ELECTRIC FIELD AND POTENTIAL DISTRIBUTION CALCULATIONS BY USING FINITE ELEMENT BASED COMPUTATIONAL SOFTWARE (ANSOFT MAXWELL 14) ALONG A 9-UNIT SILICON RUBBER INSULATOR STRING THAT IS USED IN FREEZING CONDITION. IN GENERAL, THE COMPOSITE LONG ROD INSULATOR SET FIELD DISTRIBUTION IS MORE NON-LINEAR THAN OF A SET WITH CONVENTIONAL INSULATORS. THE MAIN CAUSES OF THIS ARE MISSING INTERMEDIATE METAL PARTS AND THE DIELECTRIC MATERIAL FEATURES OF THE POLYMERIC MATERIALS IN COMPOSITE INSULATORS. BY USING THE FINITE ELEMENT METHOD (FEM) WE ARE ABLE TO CALCULATE THE REAL SITUATION NUMERICALLY. DUE TO A THICK ICE LAYER ON STRING INSULATOR, ELECTRIC FIELD DISTRIBUTION IN THIS EQUIPMENT ALTERS SIGNIFICANTLY, PARTICULARLY WHEN A WATER FILM FLOWS ON THE ACCUMULATED ICE SURFACE. MODELLING OF ELECTRIC FIELD DISTRIBUTION ALONG A STING INSULATOR WHICH IS COVERED BY ATMOSPHERIC ICE WITH AIR GAPS IN THREE DIFFERENT CONDITIONS OF CLEAN, POLLUTED AND HEAVY POLLUTED IS THE MAIN OBJECTIVE OF THIS PAPER THAT IS DONE THROUGH FINITE ELEMENT METHOD (FEM).
