Abstract：Abnormal excitation voltage waveform is found in the excitation system test of unit 6 of a gas turbine power plant. Combined with the secondary circuit of the test and the principle of demagnetization, the cause of abnormal waveform is analyzed, and the personnel are organized to check and deal with it. The results are compared and verified. Finally, some suggestions are put forward to avoid the occurrence of such incidents.
