Abstract

The technology of insulation has been evolved from the use of porcelain and glass to the polymeric materials. Since polymeric materials has been accepted as the high voltage application. A lot of study has been conducted to make an improvement to its properties, understand it performance and to develop a new composites as well and it involves in designing, monitoring and practical testing. This study will be focused on practical testing of Silicone rubber (SIR) thermoset type of polymeric material. The electrical SIR parameter to be investigated are its dielectric strength performance. In order to determine this parameter, standard test of dielectric strength is conducted, where it complying to International Standard BS EN 60243-1 : 1998 test method. All the testing procedure and specimen preparation are following this standard. The test was conducted for determining long-term dielectric strength of solid insulation material at power frequency of 50 Hertz (Hz). Three different shapes of electrode were used which are flat end shape electrode, spherical end shape electrode and pin end shape electrode. From the analysis carried out, dielectric strength of SIR using all shapes of electrode meet the minimum requirements of breakdown field strength which must exceed 10kV/mm with reference to International Standards BS EN 62039 : 2007. Then, this results of breakdown voltage can be used for determine the properties of ageing conditions, manufacturing design and other environmental condition in HV insulation application using polymeric materials.
