Liquid-Contaminant: Inclined Plane Tracking and Erosion of Insulating Materials

To find the influence of the solid insulators relative permittivity on potential and electrical-field distribution along solid insulator samples according to the ASTM D2303 Inclined Plane Tracking Test Standard is investigated. The inclined plane method is one of a few other tests that prove the material resistance to erosion and tracking caused by surface discharges. In this paper the review of inclined plane tests and the influence of additional factors were shown. A simple method for evaluating the voltage source rigidity was proposed.
