Technology ST – Hydro A headline about Hydro power As with all rotating industrial machinery Hydro power plants are prone to vibration and as with all power generation, preventing downtime is critical. Xi bring their experience of industrial process and rotating machinery and apply it to Hydro sites. Whether it is a specialist measurement to diagnose and quantify unusual behaviour or in the specification installation and operation of longer term condition monitoring systems, Xi can apply their capability to quickly and efficiently resolve and prevent issues and costly downtime. Xi’s particular expertise lies in vibration and dynamics. Extending upon more traditional routine tests Xi can look at anything from; casing vibration, Operational Deflection Shape (ODS) analysis, torsional and shaft vibration, to shaft and axial run-out. To support field measurement Xi can also simulate the plant behaviour allowing us to look at internal shaft and blade behaviour as well as wider structural responses that would otherwise be highly costly and potentially impossible to physically test.
