PROGRESS ON THE BREAKDOWN VOLTAGES AND LEAKAGE CURRENTS ANALYSIS OF MULLITE PRODUCED FROM KAOLIN

Kaolin is a clay mineral that has found its huge use in electrical insulation. In power industries, mullite insulators plays vital role during electric transmission. The transformation of kaolin to via sintering method was carried out by varying the temperature heating at interval from . mass observed have changed until complete took place 11500C. dielectric strength (breakdown voltage) analysed sending high input voltage through samples and measuring output breakdown occurred. passed occurred for almost all samples. leakage current also determined using Ohm’s law. 11500C be optimum mullite. value ( )was negligible making good material
