description The invention discloses a hollow coil cable fault detection system based on an MEMS sensor. The hollow coil cable fault detection system comprises the MEMS sensor and a data analysis unit, the MEMS sensor is arranged in an induced magnetic field of the power transmission conductor, and a signal in direct proportion to the differential of time by the current of the power transmission conductor is measured through electromagnetic induction; the data analysis unit communicates with the MEMS sensor and is used for carrying out data processing on a sampling signal of the MEMS sensor so as to obtain a parameter value of the power transmission conductor and parameter information measured by the MEMS sensor; and performing fault detection on the transmission conductor according to the waveform relationship between the parameter value and the parameter information. According to the invention, an iron core is not needed, so that at least one of ferromagnetic resonance and magnetic saturation nonlinearity problems cause
