Abstract :
A laboratory test to evaluate and compare the tracking and erosion resistance of High Voltage (HV) outdoor polymeric insulating materials is described. The test is based on combining some features of the ASTM D-2132 Dust and Fog test, and ASTM D-2303 Inclined Plane test. The experimental conditions employed can be related to actual field conditions, hence the results obtained provide a more realistic evaluation of materials´ tracking and erosion performance. Measurements of leakage current via a computerised data acquisition system, and discharge activity with a high speed camera were performed to develop a better understanding of the onset of material degradation. The materials evaluated include various formulations of High Temperature Vulcanising (HTV) silicone rubber and polyolefin polymers
