Bluetooth wireless communication and 1-wire digital temperature sensors in synchronous machine rotor temperature measurement
Marinko Kovačić, Mario Vražić, Ivan Gašparac · 2010
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 generator and the temperature measurements in rotation are presented.
