This paper presents a method of applying the reliability theory to condition based maintenance of steam turbines for the accurate identification of faults and increasing availability for steam turbines. The scope of reliability theory made use of includes statistical analysis of life expenditure data, interference modeling of probability distribution and system reliability. Some mathematical models for the application of the reliability theory to condition based maintenance are given together with some practical examples concerning machines. Condition based maintenance technique based on the reliability theory are featured by the following adavntages:physically well-defined,simplicity of mathematical expression,reliability of diagnostic results and easy to master by on site personnel. The application of the reliability theory to condition based maintenance of steam turbine has herewith provided a new and effective way of condition based miantenance in steam turbines.
