1. A probe for use in non-destructive measuring of electrical resistance of a high current electrical connection between two high current electrical conductors, each of said conductors having a longitudinal exterior surface, the probe comprising:

  • an articulated body being articulated about a longitudinal axis;

    a plurality of electrodes provided on an interior portion of the articulated body for engaging about said longitudinal exterior surface;

    connecting means for releasably connecting the articulated body around said longitudinal exterior surface, the connecting means including resilient means cooperating with the plurality of electrodes for causing the electrodes to resiliently engage said surface, the electrodes being located on the probe body to be arranged substantially evenly around and on said longitudinal exterior surface of the corresponding conductor in a plane substantially perpendicular to a current flow in said conductor; and

    resistors connected in series with each said electrode, each of said resistors having substantially an equal resistance substantially greater than a contact resistance between the corresponding electrode and the corresponding conductor, said resistors being connected to at least one common terminal for connection to a high sensitivity low resistance ohm-meter.
