Abstract
This paper presents some observation results of the
attachment test of a wind turbine blade as described in the
upgrade of the IEC-61400-24. The optical observations were
performed by means of high-speed video and UV-sensitive
photo camera. This study investigates the effects on the
leaders emerging from the blade comparing three different
air-terminals: discrete receptors, discrete receptors with
diverter strips and metallic tip. In the first two types, salt
mist pollution was applied to the blade. For non polluted
tips positive leaders appeared from receptors towards the
ground avoiding the blade surface. When the blade was
polluted additional leaders emerged moving horizontally.
Moreover, in this situation the leader progressed on the
blade surface. Pollution also produced the inception of more
leaders when the blade was equipped with discrete
receptors and diverter strips.
