HIGH-VOLTAGE CURRENT TRANSFORMER Russian patent published in 2003 - IPC

FIELD: high-voltage distribution systems. SUBSTANCE: high-voltage current transformer has cores mounted in case. Case is built of two parts joined together so that they can be easily separated. Case parts are arranged for no ability of contacting each other along their inner circumference where they form annular groove. Case parts are made of synthetic material with carbon black implanted therein. Case parts are conducting through entire structure of synthetic material or along chosen sections, or along clearly outlined areas of their surfaces.
