Abstract | Evaluating the electrical tracking and erosion resistance of polymeric housing materials is an essential task performed in the development of outdoor insulators. Tracking refers to the formation of a carbonaceous path on the surface of the insulation housing; whereas, erosion indicates weight loss of the housing material. An absolute realization of the electrical tracking and erosion resistance is not possible and therefore relative ranking of materials is the outcome that can be obtained in the standard electrical tracking and erosion tests. With the early utilization of organic insulating materials, failure due to tracking was a major concern, and therefore standard screening methods were proposed to mainly evaluate the tracking rather than the erosion resistance. Erosion is more important since the application of tracking-resistant composites compounded with high levels of inorganic fillers or possessing inorganic backbones such as silicones. |
