Wind power components get accelerated life testing
Dependability and reliability are essential quality criteria for wind power equipment. At the heart of these products and installation are a group of critical yet often hidden components such as magnetostrictive transducers and sensors used for pitch control, yaw position, speed indicators, lock pin positions and level/leak detection.
A competitive advantage goes to those systems builders who only use such transducers and sensors in their wind turbines which have demonstrated flawless function over the entire life cycle. To reach this flawless function conventional testing for product qualification within specification is often no longer sufficient. Balluff therefore routinely subjects its sensors and linear displacement systems to HALT testing in its own testing facility. Here the components are subjected to an accelerated 'aging process' within three to five days, thereby simulating the total of all load conditions within the life of a sensor in time lapse fashion. Possible weak points can thereby be reliably detected and corrected as early as the development phase. The result is sensors of unmatched quality and reliability.
In a HALT test the sample is subjected to ever increasing mechanical, thermal and combined loads at precisely defined intervals until it fails. This time lapse indicates the function and destruction limits of the product, thereby enabling the design team to greatly extend the final product's life expectancy before failure. Information about long-term behaviour is gathered, with greater reliability than the final result compared with conventional testing for product qualification within specifications.
The Balluff test fixture provides the ideal conditions for such testing. And Balluff also offers testing in its HALT facility as a contracted service.
