Insulators' pollution problem: Experience from the coastal transmission system of Crete

Electric Field Simulation Around Contaminated SIR Insulators Using MATLAB

“…The main aim of this paper is to focus on simulating the electric field (EF) distribution around a silicon rubber (SIR) insulator under various conditions using MATLAB. Insulators may fail when pollutants accumulate on their surface and certain environmental stresses occur [1][2][3][4][5][6][7][8]. These conditions are commonly seen in the field with in-service insulators located near polluting sources like coastal areas and agricultural fields [1][2][3][4][5][6][7][8] .…”

“…Insulators may fail when pollutants accumulate on their surface and certain environmental stresses occur [1][2][3][4][5][6][7][8]. These conditions are commonly seen in the field with in-service insulators located near polluting sources like coastal areas and agricultural fields [1][2][3][4][5][6][7][8] . The EF distribution is important to find the electric field stress occurring on the SiR insulator surface under various conditions.…”

“…But in the recent years, composite (SIR) insulators have gained a large share of the market. Compare to conventional insulators, silicon rubber insulators offer certain obvious advantages such as low weight, but the most significant advantage is related to their hydrophobic surface that allows them to operate fault and maintenance free in polluted areas [1][2][3][4][5][6][7][8]. To analyze the characteristics of SIR insulators, modeling and simulations were done under different contaminated conditions.…”

“…They are usually made of metal. The most commonly used housing material for composite insulators is SIR due to its properties related to surface hydrophobicity [1][2][3][4][5][6][7][8]. The effect of contamination on SIR insulator is usually analyzed by placing dust along with droplets on the surface while a voltage source is applied to one end (usually the lower electrode).…”
