  • Apparatus for measuring an a.c. current in a cable
    Patent number: 5652506
    Abstract: An apparatus for measuring an a.c. current flowing in an electric cable comprises a pair of jaws for receiving the cable and which are movable towards one another to engage the opposite sides of the cable. A potentiometer generates a signal ("cable size signal") corresponding to the relative positions of the jaws. A set of coils is provided adjacent the jaws to detect the magnetic field generated by current flowing in the cable. A circuit in the housing is responsive to the cable size signal and the voltage induced in the coil for determining the amplitude of the current flowing in the cable and displaying the same on a display.
