- In order to improve the accuracy of the current differential protection, we can detect from the current transformer which can collect reference amount and transfer current. By analysis of the equivalent circuit of the current transformer, the saturation current waveform, the saturation current of harmonic waveform and current transformer secondary circuit shunt of single-phase ground fault. Proposed impact factors, may lead to errors and corresponding solutions and measures, based on the characteristics of the current waveform and parameter has a certain value.
