Abstract
A current transformer includes a closed magnetic circuit and a secondary winding. A first part of the closed magnetic circuit completely surrounds a primary conductor, and a second part of the closed magnetic circuit forms the secondary winding. The second part of the closed magnetic circuit serves as a magnetic core of the secondary winding. The closed magnetic circuit forms a plurality of branch magnetic circuits at the second part, and a secondary winding is formed on each branch magnetic circuit. Each branch magnetic circuit serves as a magnetic core of a corresponding secondary winding. Each secondary winding is staggered with each other in at least one of the length, the height and the thickness.
