Abstract : The patent describes a technique and apparatus for identifying and accurately locating nonlinear mechanical junctions of electrical conductors whereby RF interference generated by nonlinear junctions can be eliminated. A fundamental signal is applied to a suspected junction by means of a current probe held in close proximity thereto. Receiver apparatus senses whether third harmonic signals are generated thereby. If third harmonic signals are generated the suspected junction is identified as being nonlinear and its exact location is then determined by connecting a bypassing conductor between the suspected location of the nonlinearity and ground and measuring the resultant reduced amplitude third harmonic signals.
