Performance Investigation of Non-Linear Insulator against Surface Tracking on Wind Turbine Blade Surface

Abstract:

This research work investigates the surface degradation of wind turbine blade surface insulator which is made from modified epoxy resin mixed with Zinc oxide (ZnO) and Aluminium oxide (Al₂O₃) in different percentage as a filler elements. Accelerated test with AC voltage of 4.5 kV 50 Hz with NH₄Cl saline solution using flow rate of contaminant equals to 0.6 ml/min according to IEC 60587 standard. It was found that, the solid insulators which has 30 % of Zinc oxide (ZnO) and 20% of Aluminium oxide (Al₂O₃) fillers prolong the process of surface tracking to the order of 5.41 for Zinc oxide (ZnO) filler and also to the order of 30.68 for Aluminium oxide (Al₂O₃) filler. On the other hand, if the amount of Aluminium oxide (Al₂O₃) filler is more than 20% by weight, it will lead to a rapid tracking phenomena.
