FIELD: devices for relay protection and automatic control of electric systems. SUBSTANCE: device has current transformer with short-circuited by-pass winding 3 and measuring winding 4 and second short-circuited winding. Measuring winding is located between short-circuited windings 5. Greatest effect is detected when short-circuited windings are designed as current-conducting container, first of which embraces magnetic circuit 1, while second embraces measuring winding 4, which is located over first container 3. EFFECT: compensation of dissipation flows. 2 cl, 3 dwg
