Abstract
The invention relates to electrical engineering. The current transformer comprises a measuring transformer consisting of the primary and the secondary windings, a magnet core wounded form unsplit insulation tape of the electric steel and used as a magnetizing winding. The additional transformer is introduced the current transformer, where the primary winding common with the measuring transformer is and to the circuit of its secondary winding there is a magnetizing winding of the measuring transformer.
Method for correction within prescribed range of correction of transformation coefficient, switch unit for its implementation and transformer with such switch unit
