  • A.C. field measurement system for detecting and sizing defects in a conductor via fixed orthogonal coils
    Patent number: 5574376
    Abstract: An a.c. field measurement testing system for detecting and sizing defects in a conductor includes a probe head having field coils located on a yoke so as to induce an a.c. field in the conductor and sensor coils arranged such that central longitudinal axes of the sensor coils are orthogonal one to another. The coils are wound on a former at the same location on the former and one of the sensor coils is oriented so that a longitudinal axis thereof is parallel to the induced a.c. field.
