Abstract : The patent describes a quadraxial system for measuring current transfer impedance in which a guard cylinder made of wire mesh surrounds a driver cylinder also of wire mesh and is resistively coupled to the guard cylinder. Within the driver cylinder is a sample cylinder resistively coupled to the driver cylinder and containing a calibration sample and a center conductor which is embedded within the sample cylinder. Electrical generating means is attached to the unloaded end of the driver cylinder inside a shielded room and a receiver is placed outside of the shielded room to obtain leakage readings. The current reaches the sample cylinder through the driver cylinder and the resistors coupling the driver cylinder to the sample cylinder.
