Sudden three‐phase short‐circuit current of a turbine generator was calculated by a three‐dimensional magnetic field analysis. That analysis takes into account the rotation, magnetic saturation, and eddy current at a rotor part. To compare test results and calculated results, a method was proposed for short‐circuit phase estimation at sudden three‐phase short‐circuit test by line voltage waveform of the test results. The calculated results of short‐circuit current waveform are in good agreement with the test results. © 2005 Wiley Periodicals, Inc.
