A new twist in torsional vibration shaft monitoring
TDMS Installations and torsional testing stories
The situation: Von Mises stress calculations on Hydro unit forced plant operators to run well below rated capacity of 57.5MW. Running at 55MW, the rotor was calculated to be exceeding the material limits of 8000psi shear and 13,333.33psi von Mises combined stress when running at capacity. The solution: live torque monitoring of the shaft (as … Continue reading Success Story: Hydropower output limitation lifted using TDMS data
Recently we helped out our neighbors to the north with Hydro TG torsional monitoring in the most prestigious powerhouses in North America. Our friends at OPG were interested in monitoring TG performance and civil structure performance on the Niagara Sir Adam Beck plant. The installations were performed in conjunction with Electric Power Research Institute (EPRI) … Continue reading OPG’s Sir Adam Beck Generating Station
This was a particularly challenging telemetry installation that we had the pleasure of solving for AEP nuclear. The installation was conducted in-situ in a bearing housing betwixt an oil deflector plate and the housing wall. The cook bearing 5 site was the grave of previous mortal attempts at telemetry measurements- This was a job for … Continue reading AEP DC Cook Unit 2 install
