Abstract
This paper presents the preventive measure and the cause for field coils breaking away from the rotor, which lately occurred when No.1 hydro generator was operating in Chung-Ju Dam No.2 Hydro Power Station. In findings, we ascertained the truth of contact between rotor rim and field coils, and think that field coils will break away from the rotor because of mechanical stress according as continuous operation after completion. 1985. Therefore, we conclude that the preventive measure for such a phenomenon is that stopper should be installed between rotor rim and field coils, and bolts should be tightened because of operating characteristic however there are not the design standards for installing stopper in generator rotor internationally.
