The invention relate to the technical field of current measurement, in particular to a dual-winding Rogowski-coil electronic current transformer with a differential amplification circuit. The dual-winding Rogowski-coil electronic current transformer comprises a Rogowski coil framework, wires are closely and parallelly wound around the framework, and the wires are dual enameled wires or are insulated in surface layers. Differential signal processing is achieved by an integrated differential amplifier, a hardware implement mode is employed, single-coil induction voltage output is changed to dual-coil induction voltage output of dual lines which are wound in parallel, the two coils output differential voltages, front amplification employs the differential amplifier, and a sampling signal canbe truly reduced; and the differential amplifier is a symmetric circuit, zero-point drift can be suppressed, so that drift signals offset each other, the dual-winding Rogowski-coil electronic currenttransformer has the characteristic of common-mode interference resistance, the sensitivity of the Rogowski-coil electronic current transformer is doubled, and the linearity of the Rogowski-coil electronic current transformer also can be improved by one order of magnitude.
