る発電機のステータコイルの温度監視装置。 A temperature detector that detects the temperature of the stator coil of the generator, a temperature detector that detects the temperature of the cooling water that cools the stator coil, a current converter that detects the load current of the generator, and each of these detectors. In a monitoring device that monitors the temperature of a stator coil of a generator based on data, the temperature of the cooling water of the stator coil of the generator is a linear function, and the load current of the generator is a linear function of the square of the linear lag. A calculation section that calculates the monitoring level as a function is provided, and the monitoring level obtained by this calculation section is compared with the temperature of the temperature detector of the stator coil of the generator, and if the temperature of the stator coil is higher, the temperature is determined. A temperature monitoring device for a stator coil of a generator, characterized in that it includes a comparison section that outputs an abnormal output.
