Investigation of stator coil and lead temperatures on high voltage inside large power generators via use of fiber Bragg gratings
SENSORS, 2002 IEEE - Tập 2 - Trang 1603-1607 vol.2
Tóm tắt
This paper reports on the first realisation of embedding fiber Bragg grating temperature sensors inside the stator bars and onto the leads of a 200 MVA air cooled power generator. The worlds first measurements of the conductor temperature at high potential during a generator prototype test run demonstrates the feasibility and importance of this measuring technology.
