    Blown fuses of main incomer in turbocor compressor

    Today, I turned on 3phase supply to the turbocor compressor, at the same time, two fuses of the compressor found blown, The compressor first converts ac to dc, by the application of SCR, then stored to dc bus and then fed to motor through igbt, last time same fuses were blown out, but everything found ok, and machine too was working ok, What will be the reason behind the blown fuses?
