Abstract: A method is presented. The method includes selecting a first window of signals and a second window of signals from clearance signals representative of clearances between a rotating component and a stationary casing surrounding the rotating component, determining a first signed average power value corresponding to the first window of signals, and a second signed average power value corresponding to the second window of signals, determining a resultant value based upon the first signed average power value and the second signed average power value, and determining one or more defects or potential defects in the rotating component based upon the resultant value.
