FIELD: measurement technology; chemical and metallurgical industries. SUBSTANCE: information about current is obtained by results of measuring the intensity or induction of magnetic field at n separate points arranged over outline around buses carrying current. Outline form is selected to be either round or square. In the last case points are located in the middle of every interval obtained after division of every side into n/4 parts. Number of points selected in this case is equal from 12 to 20. EFFECT: higher measurement results. 4 cl, 7 dwg
