This paper addresses the usage of digital temperature sensors in rotor temperature measurement. A rotor temperature measurement system had to be developed because of the complete synchronous machine thermal analysis. Rotor temperatures are measured using multiple DS18B20 digital thermometers and sent via a wireless link to the host. The measurement system has been mounted on a 400 kVA synchronous...
After 40 years, the laboratory of electric machines and drives had to be rebuilt. So it has been decided to do it from scratch. Therefore some other issues had to be taken into consideration. This paper will present approach to laboratory design regarding didactics, methodology and praxis.
This paper addresses some of the problems related to direct temperature measurement of synchronous generator excitation winding in rotation. Excitation winding temperature is used for determining the dynamic limit in a PQ diagram. The paper also addresses procedures of improving the accuracy of surface temperature measurement using the DS18B20 digital temperature probes. The paper also provides experimental...
