PRINCETON JUNCTION, N.J., March 15, 2010 (GLOBE NEWSWIRE) -- MISTRAS
Group, Inc. (NYSE:MG), in collaboration with Florida Power & Light
Company, has developed an on-line monitoring system for detection of
mid-compressor stator vane cracking in GE 7FA combustion turbines. The
Acoustic Combustion Turbine Monitoring System, or ACTMS, is designed to
detect crack propagation in compressor stator vanes prior to airfoil
failure, thus enabling corrective action to avoid extensive downtime
and repair costs.

ACTMS crack detection algorithms continuously monitor for signatures of
cracking activity while discriminating against normal turbine operating
noise. Multiple sensors, which are mounted externally on the
compressor, enable ACTMS to locate and display the position of cracking
events for engineers to quickly diagnose the indication and recommend
corrective action. ACTMS can be interfaced to plant data networks or
the turbine control system for warning and trip functions.
