【Abstract】 This paper describes the test methods and the various test results for the deter- mination of the negative sequence current capability of type QFQ-50-2 turbo-generator by equivalent loss method.The current of the rotor slot wedges are measured by mag- netic test coils,and the eddy-current field of the rotor are calculated by finite ele- ment method.By the comparison of the calculation results with the measured values, the accuracy of the calculating methods is satisfactory.更多还原
