摘要： PROBLEM TO BE SOLVED: To provide a device for measuring the temperature of a winding conductor for AC rotary electric machine, and a measuring method capable of accurately measuring resistance value to the order of 10 -7 Ω at the minimum when measuring the temperature of a stator winding having a low resistance value to the order of 0.0001 Ω to 0.001 Ω. SOLUTION: The device 30 for measuring the temperature of stator winding conductor is equipped with a measuring basic circuit 36 provided with a variable DC voltage supply means which can supply DC voltage equivalent to or more than AC voltage generated in a three-phase short circuit 33 during three-phase short circuit energizing operation, a limiting resistor 34 limiting the AC voltage generated in the three-phase short circuit 33 and a shunt 35; and a voltage and current measuring means 38 provided with a measuring channel 43 drastically attenuating an AC component superposed on a measurement signal with respect to a DC component, a digital recorder 45 with high resolution and a data processing device 46 processing the measurement signal. Accordingly, since the resistance value of the stator winding 32 can be accurately measured to the order of 10 -7 Ω at the minimum, temperature change of the stator winding 32 can be accurately measured.
