FIELD: electrical and radio engineering. SUBSTANCE: current measuring circuit has transformer 3 with mutual inductance, integration circuit 2 and pseudorandom circuit 1 which adds meander oscillation to signal of transformer 3 in front of input of integration circuit 2 so that integration circuit 2 generates signal presenting measured current disturbed by triangular pseudorandom signal. EFFECT: problem of complicity and doubling of components is solved with integration of advantages coupled to transformers with intercoupling and to use of pseudorandom signals. 7 cl, 2 dwg
