In addition, the incorporation of these fillers into a rubber formulation lowers the cost of these compositions making it an attractive choice for manufacturers of outdoor insulation. Although various laboratory tests have shown that fillers are beneficial in preventing tracking or erosion, studies have not demonstrated which of the two materials perform better in actual field applications. Furthermore, some recent studies have shown that the presence of ATH is really not required to enhance the resistance to tracking and erosion. The aim of the present study is to compare the performance of filled and unfilled silicone rubber using the inclined plane tracking and erosion test. Material samples, prepared with either silica or alumina trihydrate are tested while a data acquisition system monitors the voltage and leakage current. The loss of material due to erosion is determined and correlated with the energy of dry-band arcing discharges.","PeriodicalId":112180,"journal":{"name":"2001 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat.

Such materials are currently being developed for power-ground decoupling in electronic circuits operating at microwave frequencies. In order to extend the measurements to the microwave range, we developed an appropriate expression for the input admittance of a thin film capacitance terminating a coaxial line. The theoretical model treats the capacitance as a distributed network and correlates the network scattering parameter with complex permittivity of the specimen. The method eliminates the systematic uncertainties of the lumped element approximations and is suitable for high frequency characterization of low impedance substrates with high value of the dielectric constant. The complex permittivity was measured at frequencies of 100 Hz to 10 GHz for films 100 /spl mu/m thick, having the dielectric constant of 4 to 40, and was fitted to a dielectric model expressed as a combination of Havriliak-Negami functions. An intrinsic high frequency relaxation process has been identified. It was found that the position of the loss peak depends on the relaxation of polymer matrix, while its magnitude is amplified by the permittivity of the ferroelectric component.","PeriodicalId":112180,"journal":{"name":"2001 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat.
