Abstract

The invention relates to a method for inspecting especially a gas turbine installation or steam turbine installation. An actual condition of a component of the turbine installation is determined using a suitable system, the determined actual condition is compared with a predetermined desired condition of the component, and the result of comparison between the actual condition and the desired condition is used to determine whether an overall inspection of the turbine installation is required. The component is a guide vane whose angular position in relation to the direction of influx is the actual condition to be determined. The actual condition is determined by an imaging device. The invention also relates to a turbine inspection system for carrying out the method.
