Abstract :
The influence of electrode coating on the leakage current of three polymer insulating materials, namely, polystyrene, (PS), polyvinyl chloride (PVC), and polymethylmethacrylate (PMMA), is investigated. The insulating materials have been subjected to alternating voltage (50 Hz) under inhomogeneous field conditions (rod-plate electrode system). Experimental investigations of the effect of specimen thickness on leakage current and flashover voltage have been carried out under bare electrode conditions as well as under coated electrode conditions. The results illustrating the effect of electrode coating on leakage current and surface flashover voltage are presented and discussed
