  • Method of detecting the defects in a dielectric coating at the surface of an electrically conductive underlayer
    Patent number: 4584521
    Abstract: The method consists in placing a conductive underlayer (1) coated by a dielectric layer (5) in a conductive medium in which an excitation electrode (2) is positioned at a distance from this underlayer (1). This underlayer (1) and this excitation electrode (2) are being connected to the corresponding terminals of an alternative-current generator (4) and between this electrode (2) and this underlayer (1) one interposes a catcher coil (6) oriented in a plan perpendicular to the electric field lines and a potential-measuring electrode (7) in the opening of said coil (6) and one determines the impedance resulting from the voltages and currents detected.
