| description | The invention relates to the technical field of circuit experiment equipment, in particular to a non-contact micro-current measurement system based on a Rogowski coil. The system comprises a Rogowski coil, an amplifying circuit module, an integrating circuit module and an oscilloscope, and is characterized in that a to-be-measured current unit passes through the middle portion of the Rogowski coil, the Rogowski coil is used for detecting the current signal of the to-be-measured current unit, the amplifying circuit module is used for amplifying the signal, and the integrating circuit module is used for carrying out integral reduction processing on the current amplifying signal to obtain a current reduction signal. According to the invention, the Rogowski coil is used for detecting the current signal of the to-be-measured current unit, the detected signal is amplified through the amplifying circuit module, and then the integrating circuit module is used for integral reduction, so that the precise measurement of |
