METHOD AND APPARATUS FOR CHECKING THE ELECTRICAL CONTINUITY OF A DEVICE COMPOSED OF ELECTRICALLY CONDUCTIVE MATTER BY MEASURING THE IMPEDANCE

摘要

1. Method for checking the electric continuity of an electrically conducting material device, in which a current (I) is injected between two points (Ao, Bo) of said device and the resulting voltage (U) between these points is measured, characterized in that said current (I) is an AC current and in that its pulsation (omega) is chosen sufficiently large so that the impedance (Z) between said two points (Ao, Bo), measured by the ratio of said voltage (U) to said current (I), may be considered as being equal to the product of the inductance of the path of the current between said points multiplied by said pulsation (omega).
