Abstract
A method for detecting core faults includes (a) positioning a magnetic yoke near at least one tooth of the core, the magnetic yoke being wound by a winding; (b) supplying current to the winding to inject magnetic flux into the at least one tooth of the core; (c) measuring a signal resulting from the injected magnetic flux; and (d) using the measured signal to detect core faults.
