Mechanical vibration. Measurement and evaluation of machine vibration - Machine sets in hydraulic power generating and pump-storage plants Ingestion-build-132972 BS EN 1747-11 specifies requirements1 Scope This document provides guidelines for evaluating the vibration measurements made at the bearings, bearing pedestals or bearing housings and also for evaluating relative shaft vibration measurements made on machine sets in hydraulic power generating and pump storage plants when the machine is operating within its normal operating range. The normal operating ranges for each type of turbine covered by this document are defined in Annex A. This
