Description

Conventional eddy current methods, using single-frequency excitation employ instruments which monitor the phasor value of the impedance, or impedance plane trajectory. Changes in the test specimen or test conditions result in a change in the value of the impedance. The monitored value of the impedance traces out loci which are generally unique to the cause of the change in impedance. In the event that a change in test conditions produces a locus similar to a locus produced by a change in the test specimen, an alternative test must be developed.
