Abstract
Electrical continuimeter device for checking the electrical continuity of a conducting layer covering a structure having conducting and non-conducting parts, said conducting layer being covered by an insulator layer. The device comprises a pick-up with an inner and an outer coaxial electrodes to be put on the insulator layer. A supply alternating voltage is applied between the inner electrode and the ground terminal of the structure developing a first voltage across a load resistor and a second voltage between the outer electrode and the ground terminal is measured. Components of the second voltage respectively cophasal and in phase quadrature with the first voltage are generated and these components are divided by the first voltage, thus providing the resistive and reactive components of the ground impedance.
