<p>PROBLEM TO BE SOLVED: To reduce a loss generated in a shield winding, size and weight of current transformer and its cost. SOLUTION: A shield winding 3 is divided into shield winding pieces 3a to 3d. The divided parts are arranged at A part near the outermost outer conductor 5 in the shield winding 3. The shield windings 3a and 3d nearest the outer conductor 5 become farther from the outer conductor 5 than heretofore and their directions are changed, so that the magnetic combination to the outer conductor 5 becomes weak and the induced current becomes small, thereby reducing a loss.</p> |
