| Abstract: | This paper presents a new method for analyzing and calculating the specialties of power transformers under the effects of Geomagnetically Induced Current(GIC). The authors combine the equivalent magnetic circuit in time domain with equivalent electric circuit in frequency one, and use it to analyze and calculate the specialities of a three-phase transformer successfully. The nonlinear model, the calculation way are given. The comparisons between the simulation results and the test ones justify the proposed method. |
