A method of detecting and positioning an insulation failure of an aircraft generator is provided, comprising: S1, for each stator slot in the aircraft generator, wrapping one semiconductor layer on a surface of an external insulation layer of each copper conductor in the stator slot; S2, for each semiconductor layer, partitioning the semiconductor layer to obtain a plurality of zones, disposing a resistor-inductance branch network in each zone, and connecting the resistor-inductance branch networks to form an insulation failure detection circuit; S3, supplying power to a three-phase winding of the aircraft generator from an external power source; S4, determining whether an unearthed voltage is present in four end corners of the insulation failure detection circuit; if not, returning to S3 for further powering; if yes, outputting a detection result and collecting an insulation failure position with potential change and difference in the insulation failure detection circuit as a positioning result.
