Abstract
A shunt for measuring current passing through a conductor. The shunt includes a first section and a second section connected in series with the conductor, and a coaxial cable connected between the first and second sections. An outer conductor of the first section surrounds an internal conductor having a resistance lower than that of the outer conductor of the first section. An outer conductor of the second section surrounds an internal conductor having a resistance higher than that of the internal conductor of the second section. The dimensions of the first and second sections are the same. An internal conductor of the cable is connected between the two sections, and an outer conductor of the cable is connected to the outer conductors of the two sections. The voltage across the outer and inner conductors of the cable is proportional to the current passing through the conductor.
