Abstract
A system includes multiple sensors configured to measure one or more characteristics of a rotating o reciprocating systems. The system also includes a monitoring system configured to monitor a health of the rotating system. The monitoring system includes an input interface configured to receive multiple input signals from the sensors. The monitoring system also includes a processing unit configured to identify a fault in the rotating system using the input signals. The monitoring system further includes an output interface configured to provide an indicator identifying the fault. The processing unit is configured to identify the fault by (i) generating a pressure-volume diagram from a fusion of the input signals and comparing the pressure-volume diagram to a previous diagram to determine changes in the diagrams and/or (ii) normalizing the input signals and using the normalized input signals to identify a defect and calculate a confidence level of the defect.
