1. A method for dynamically configuring a diagnostic apparatus for automatically and systematically diagnosing faults in a rotating machine, comprising:
- creating definitions for all major components of the rotating machine and storing the definitions in a memory of the apparatus;
constructing search equations for extracting salient observations from machine measurements acquired from the rotating machine and storing the search equations in the memory; and
specifying rules for deducing machine signatures from the salient observations and identifying faults in the rotating machine from the machine signatures, and storing the rules in the memory.

Abstract
A technique for detecting problems in a rotating machine is configured by the user specifying components and the functional characteristics of a particular installation of a rotating machine. The machine specification are used to identify salient observations that can be derived from measurement data regarding the machine performance. Rules are specified by the user to deduce machine signatures from the salient observations and detect problems evidenced by the machine signatures.

17. A method for automatically and systematically diagnosing faults in a rotating machine using a diagnostic apparatus, comprising:
-
performing a set-up phase for the apparatus, the set-up phase including;
constructing definitions of major components of the rotating machine, constructing search equations for extracting salient observations from machine measurements, and specifying rules for deducing machine signatures from the salient observations and identifying faults in the rotating machine from the machine signatures; and
performing an analysis phase with the apparatus, the analysis phase including;
acquiring machine measurements using a plurality of sensors mounted on the rotating machine and supplying the machine measurements to the apparatus, extracting salient observations from the machine measurements using the search equations, deducing machine signatures from the salient observations using the signature rules, and identifying faults in the rotating machine using the rules. - View Dependent Claims (18, 19, 20, 21, 22)
