摘要： A method for determining a temperature at a predetermined location in a winding of subconductors of an electric machine is provided where each subconductor is encased in electric subconductor insulation. The method includes predetermining the location between one of the subconductors and the associated subconductor insulation; arranging, in said winding, an optical fiber with a sensor material piece that is fixed to the predetermined location, the optical properties of said sensor material piece being temperature-dependent and uninfluenced by stretching; exposing the sensor material piece to light via the optical fiber such that, following an interaction with the sensor material piece, light is emitted from said sensor material piece; measuring the spectrum of the light; and using this spectrum to determine the temperature at the predetermined location.
