Method and device for detecting cooling system failures of a turbine

摘要

Process for detecting faults in a cooling air system of a turbine comprises determining the cooling air consumption at each turbine blade (3) for at least some of the turbine blades. An independent claim is also included for a device (1) used for detecting faults in a cooling air system of a turbine. Preferred Features: Cooling air consumption is determined by a measuring device (5) arranged in a cooling air channel (7) of the respective turbine blade and having at least one sensor wire (9) made of Kantal and/or Invar.
