Nanodielectrics for use in HVDC power systems and their structure-property relationships using Chemometric methods

摘要

This paper deals with the development of new thermoset based nanocomposite electrical insulation materials for HVDC power transmission applications. A wide range of insulation properties were determined and some are discussed. With sufficient understanding of these properties, their trade-offs and process requirements, it is possible to obtain balanced materials for specific use in improved HVAC or HVDC components. It has been demonstrated that the application of multivariate statistical analysis (MVSA) methods can establish relationships between key properties and molecular information obtained spectroscopically. It was found that the electrical properties of a material are heavily dependent on the chemistry of the materials system and its degree of curing with particular factors responsible for the greatest improvement in electrical properties, such as electrical breakdown strength.
