Abstract

ABSTRACT:- In this research study some electrical properties of porcelain bodies prepared from Iraqi raw materials, where the observed changes in these properties change the conditions of the formation of the porcelain body and conditions of measuring these properties, the same conditions that are likely to have been the separation during the currency of an electrical insulator. And found that the dielectric constant decreases the increased frequency of measurement and drop the smaller-sized granular material to potash feldspare. Also found that the loss factor of the body increases with increasing porosity of porcelain body, and dielectric strength of porcelain insulator less with increasing temperature and increases with increasing the thickness of the insulator.
