Abstract: First results are reported of tests with a patterned texture, silicone rubber surface. Such texturisation is designed to reduce leakage current density and to increase creepage distance, with the aim of improving pollution performance of polymeric insulators. The tests are of two kinds: a) inclined-plane tests (IEC 587: 1984), to determine the erosion rate and tracking of rectangular samples of insulation materials when these are subjected to surface discharges. Such samples have been prepared both with a conventional plane surface and with a textured surface for comparative tests; b) clean-fog tests (IEC 507: 1991) that use an initially dry pollution layer of known salinity. Here, plane and textured samples have been used for comparative tests, where leakage current and discharge activity are monitored during the generation of the fog.
