Non-Linear Insulator Performance of Wind Turbine Blade Surface against Lightning Strike

Abstract:

This research work investigates the surface degradation of blade specimen which is made from epoxy resin mixed with non-linear fillers of Zinc oxide, Aluminium oxide and Sodium silicate in different ratio percentage. Test on surface trackability of each specimen according to IEC 60587 standard. Then, choose the best specimen which has achieved a high tracking resistance to test against lightning impulse voltage according to IEC 60243-3 at ± 60 kV_peak. A comparison has been made with the pure epoxy resin specimen as a controlled sample. The results showed that, the epoxy resin specimen with the ratio of 40% by weight of Aluminium oxide filler slow down the tracking process better than other specimen type. And from the result of lightning impulse withstand voltage test, it is found that all of the specimen were not affected.
