PURPOSE: An instrument transformer is provided to be capable of measuring a high voltage or sensing a line trouble by installing a transformer at a gas insulated switchgear. CONSTITUTION: An input terminal part(1) penetrates the center of an upper fixing plate(61) so as to be fixed, and a silicon insulation cap(12) is inserted in an outer side of the input terminal part(1). A charge part mounts a multi contactor(11), and the input terminal part(1) is inserted in a power socket mounted at a gas insulated switchgear. A shield(13) is embedded in a rear body of the input terminal part(1). A primary winding(41) consists of one. An iron core(43) is placed at upper, lower and perpendicular directions of the primary winding(41). Terminals(5) are fixed at a left side of a main body(3), and a terminal is fixed at a right side thereof. A ground terminal(8) is placed at a lower center of a lower fixing plate(62), and a body outside is coated with a metal plate(9).
