<br/><br/> The study included optimize the grading ring to reduce the electric field on 220 kV polymer suspension insulator in electrostatic physics by COMSOL Multi-Physics Program after drawing it on Auto CAD 2D programme finally reached to the optimum case of electric field when it was clean, then pollution was added to show effect of pollution on electric field distribution, the pollution was water drops with different shapes or cases, also conductivity studied to prove no changing on electric field in electrostatic physics. Therefore, the optimum case was changed after adding pollution on insulator surface to prove the pollution is effect on the electric field distribution then shown the optimum three cases when the insulator was clean and the optimum three cases when it was polluted
