Academic background
Christopher Crabtree received his MEng degree from Durham University in 2007 and is currently completing a PhD in the Energy Group at Durham.

Research topic
The development of condition monitoring techniques for wind turbines

Research background and objectives
Christopher’s research has focussed on the development of condition monitoring techniques for wind turbines, mainly through the use of high sampling rate data. A condition monitoring test rig has been developed at Durham University which allows variable speed, variable load conditions to be emulated, bringing its operational conditions close to those experienced on an operational wind turbine. Electrical and mechanical faults can be applied to the test rig including rotor asymmetry and gear tooth damage. Techniques for frequency analysis of non-stationary, operational condition-related signals have been developed as a move towards automated condition monitoring.
