Abstract
A technique for detecting defects in aircraft wiring, such as for detecting partial discharges or arcing in wiring or cables is disclosed. A high frequency current transformer (HFCT) is fixingly positioned in contact with a wire so that the wire is encircled by the HFCT. Partial discharges from a damaged wire so encircled will induce a current in the HFCT proportional to the current of the discharge. The HFCT includes a conductive coil-like pattern formed onto a flexible insulating material. The insulating material has slits between each coil-turn. The HFCT also includes a core of flexible material fitted between the coil-turns through the slits.
