Abstract

A brief review of methods and means of diagnostics and monitoring of steam-turbine blades is made, informational criteria for determination of the defective status of blades are defined only by peripheral sensors, and a developed block diagram is presented for a system in the form of a software package to be used in monitoring the deformed status of blades and to ascertain their defective status.
