A new twist in torsional vibration shaft monitoring
TDMS Installations and torsional testing stories
We are proud to announce that we have successfully installed the TDMS system and will performing torsional testing on Vogtle unit 4 turbine. It is an honor to work on one of the new US nuclear units in 40 years. The installation was a little challenging due to it having to be performed inside a … Continue reading TDMS installation Vogtle Unit 4
Entergy invited Suprock to install our TDMS system at their plant due because our wireless powered telemetry is capable of measuring torsional vibrations long term. They have a new upgraded turbine en route and are using the TDMS system to ensure smooth operation till it’s time to install the new rotor train. It was a … Continue reading Waterford 3: Another successful TDMS install
Joe and Francesco took the country roads down to West Virginia and helped our friends at AEP Amos plant with a TDMS install. This was a combined TDMS/pressure sensor install for the purpose of studying a possible steam flow issue and how it may be affecting torsional vibrations and with it, the health of the … Continue reading TDMS install in West Virginia
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
