Indirect measurement of generator rotor temperature

In large generator rotor temperature directly unpredictable situation,made a kind of indirect temperature measurement principle,namely the use of the relationship between resistance and temperature,resistance and voltage,current relationship,through the measured winding voltage,current,and then converted the rotor temperature.The specific implementation methodology is based on the principle of indirect temperature measurement,select the necessary hardware,to build measure devices,and then be written the software to achieve the purpose of generator rotor temperature.The on-site test and simulation concludes that this method is simple,feasible and reliable.
