Traceable mechanical and electrical power measurement for efficiency determination of wind turbines

Project: EU project

Project Details


Practical and traceable testing processes to ensure high reliability of wind power production.
The wind energy sector needs standardised tests for the efficiency determination of nacelles and their components on test benches in order to improve the efficiency of wind turbine drive trains, quicken the development cycles and shorten the time to market.
Project will establish practical and traceable methods for torque measurements up to 5 MN m and rotational speeds covering the operational speeds on low-speed and high-speed shafts.         
VTT MIKES will establish torque transfer standards with a measurement range up to 100 kN m.
Call 2019: Metrology for Energy
