<p>PROBLEM TO BE SOLVED: To dry a stationary induction machine while restricting occurrence of rust by hardly producing dew condensation.SOLUTION: This invention comprises the steps: of arranging a temperature sensor at a part covered by a winding of iron core (S100); operating a heating mechanism for heating the iron core and the winding (S110); stopping the heating mechanism when a difference between a temperature measured value of the temperature sensor and a dew point temperature measured by a dew-point thermometer reaches a prescribed first difference (S140, S150); and after stopping the heating mechanism (S150), restarting the heating mechanism when a difference value between a temperature measured value of the temperature sensor and a dew-point temperature measured by the dew-point thermometer reaches to a prescribed second difference (S160, S110).</p> |
