We have investigated the influence of a fault current limiter (FCL) upon the relationship between the electrical air-gap torque and the shaft torsional torque of the synchronous generator in a consumer system connected to a 6.6 kV utility distribution system. We found that the suppression mechanism of the shaft torsional torque was classified by a natural oscillation frequency of the synchronous generator. It was shown that the suppressing effect on the maximum value of the shaft torsional torque τ_sm is largely determined by limiting of the average value of the electrical air-gap torque τ_e in case that a natural oscillation frequency f₀ of the synchronous generator is small. For higher f₀ being close to a system frequency, it was shown that it is useful for the suppression of the τ_sm to suppress the the instantaneous value of the τ_e.
