Abstract
A high voltage current transformer, and method of constructing same, including a primary winding having concentric leads, and a secondary winding on a magnetic core which is inductively linked with the primary winding. The magnetic core is a wound, two part core, with the two core parts being joined by stepped-lap joints. The secondary winding is a distributed winding having turns which are uniformly distributed about the complete magnetic circuit of the magnetic core. The conductor of the secondary winding is severed and the associated ends electrically re-connected, each time the conductor passes a stepped-lap joint.
