FIELD: electric measurement technology, measurement of heavy direct currents. SUBSTANCE: gear is fitted with transducer of variable component of current in the form of current transformer whose output signal is employed to compensate for signal of variable component of measured current in output voltage of Hall generator. Transducer of variable component of current is placed between ground bus and input of current-to-voltage converter. Voltage follower and summing amplifier are parts of each measurement element of magnetic induction. EFFECT: increased functional accuracy of gear. 5 dwg
