Abstract
A current transformer includes a pre-formed core forming a closed loop with a flexible axially wound secondary winding. A continuous length of wire is axially coiled around a flexible bobbin to form a secondary winding. The resulting secondary winding may be slid onto the closed loop of the pre-formed core. The flexibility of the axially wound secondary winding facilitates conformity to a non-linear shape of the pre-formed core.
