Coaxial resistor for measuring electric current, has low impedance resistance unit arranged in conductor lying outside resistor and switched in series with conductor lying outside resistor

摘要

The resistor (1) has conductors (10-12) lying inside and outside the resistor. The conductors are arranged coaxially to each other and are switched in a sequence. The conductors lead the current to magnetic field compensation in opposite direction. A low impedance resistance unit (13) is arranged in the conductor lying outside the resistor and is switched in series with the conductor lying outside the resistor.
