CURRENT SENSOR Russian patent published in 1997 - IPC

FIELD: instruments. SUBSTANCE: sensitive element of device is located inside autonomous capsule which is made from non-magnetic material. Said capsule during device operations is located inside chamber of magnetic flux concentrator, which is made from magnetically soft material and is U-shaped. Sensitive element is designed as inductance coil which core is oriented so that projection of vector of magnetic flux which is generated by current which runs through conductor to be measured is non zero. EFFECT: possibility to measure heavy currents without non-linear distortion, simplified design, facilitated manufacturing. 8 cl, 3 dwg
