Abstract
A current transformer includes first and second bobbins, and a secondary winding. The first bobbin includes a first tube defining a first longitudinal axis. First and second flanges are disposed on first and second ends of the first tube. The first tube, the first and second flanges collectively define a first slit along the first longitudinal axis. The first slit allows receipt of a primary conductor into the first tube. The second bobbin includes a second tube rotatably received about the first tube. The second tube defines a second slit along the second longitudinal axis. The second slit allows receipt of the primary conductor into the first and second tubes. The secondary winding is wound about the first bobbin and extends along the first longitudinal axis, passing through the first tube and over the first and second flanges. The second tube rotates about the second longitudinal axis relative to the first tube.
