Description

Coil eddy-current (CEC) technology generates real and complex reactances of the search coil. These reactances are frequently plotted in a complex-impedance (C-I) plane with inductive reactance as the ordinate and resistance as the abscissa. This plane is a useful tool in nondestructive evaluation (NDE), and it is known to virtually all NDE technicians using electromagnetic fields. The complex-impedance plane is generally used to establish the operating conditions for particular eddy-current coils and for particular NDE problems. It can also be used to establish the effect of lift off and to identify flaws.
