| Abstract: | Shortly after a 300MW turbogenerator was put into operation, the temperature of the stator coils in the 28th slot was found to be higher than that in other slots. The temperature deflection rose with the load increasing. It was determined by the method of hot water flow, that the temperature deflection was caused by blocking in the water circuit of the stator coil. The judging procedure is described in detail. |
