Abstract
The invention relates to a method for monitoring the condition of turbines using their coasting time. The aim of the invention is to ensure that the monitoring process is as sensitive as possible with low resource requirements. To achieve this, the measured coasting time (tmeasured) is corrected by a correction member, in which the temperature of the medium (Tmedium) in the turbine that has likewise been measured, is taken into consideration and compared with a reference value.
