发明名称 Stationary Induction Electric Machine
摘要 A stationary induction electric machine which makes it possible to detect partial discharge in the stationary induction electric machine with favorable sensitivity and easily retrofit an electromagnetic wave detection sensor to the already installed stationary induction electric machine is provided. The stationary induction electric machine has in a tank a core including a plurality of core legs and a winding wound around the core legs. A polymer bushing 6 is secured on the upper face of the tank through a support fitting 18. The polymer bushing 6 is provided with an electromagnetic wave detection sensor 11, which is placed in a position where the support fitting 18 is avoided.
