    Current Transformer

    The Current transformer(CT) is a type of instrument transformer that is designed to reduce or multiply an alternating current. In other words it produce an alternating current in its secondary winding which is proportional to the current being measured in its primary winding.

    Current Transformer are the current sensing units of the power system and are used at generating stations, electrical substations,power plants and in commercial and industrial power distribution.

    The Current Transformer is used with the alternating current instrument,meters or control apparatus where the current to be measured is of such magnitude that the meter or instrument coil can’t conveniently be made of sufficient current carrying capacity.
