Abstract
A system and method for monitoring a gap size of a gap between a seal holder and an adjacent disk in a compressor section of a gas turbine. An imaging device is used to generate at least one image of the gap, wherein a calibration image of the gap is generated when the gas turbine is in a cold state to provide a calibration gap size. An operational image of the gap is also generated when the gas turbine is in operation to provide an operational gap size. In addition, an enclosure that houses the imaging device is attached to an access port formed in the compressor section to provide a view of the gap for the imaging device. Wear is detected in a hook section of the compressor section when the operational gap size is less than the calibration gap size.
