FIELD: measurement of currents in electrophysical installations. SUBSTANCE: device has n magnetooptical transducers with sensing element, made as extended light guide from magnetooptical material, and measuring-and-computing unit. Position of optical input of each of n light guides of magnetooptical transducers coincides with optical output of adjacent light guide so that all light guides form closed coupled circuit embracing only current conductor with current being measured. Outputs of magnetooptical transducers are connected to respective inputs of measuring-and-computing unit. EFFECT: increased maximum value of measured current. 1 dwg
