A fluxgate current sensor and a current measurement method, wherein the fluxgate current sensor includes a magnetic probe and an excitation and detection circuit, and the magnetic probe includes an excitation iron core and an excitation coil, the excitation coil is connected to the excitation and detection circuit, the excitation and detection circuit is used to output alternating excitation voltages to the excitation coil, and the excitation coil is excited to generate alternating excitation currents and cause the excitation iron core to reach saturation alternately; the excitation and detection circuit is further configured to convert the excitation currents flowing through the excitation coil, into equivalent differences of two currents, so as to calculate average values of the excitation currents flowing through the excitation coil via differential equivalent currents, thereby calculating to-be-measured primary currents by the average values of the excitation currents.
