概要
This study proposes an electromagnetic method for the evaluation of the condition of the turbine in a nuclear power plant. Experimental re sults of a small turbine driven by an electric motor are shown in this paper. The results show that it is possible to detect the movement a nd condition of the impeller by applying the electromagnetic evaluation method. Moreover, an excitation experiment shows that the higher o rder vibration of the impeller can be detected and the distinction of the condition of with and without enforcement excitation is possible.
