As an alternative to porcelain, composite insulators can be supplied as an option by most of the post type CT manufacturers. These are typically of silicon rubber material which has the advantages of being lightweight, superior in terms of pollution performance and more importantly are inherently safer then porcelain insofar that they will not shatter or fragment.
This project will investigate the impact of replacing current transformers with porcelain insulators for composite insulated current transformers and how these composite insulators will behave in typical busbar arrangements under static and dynamic load conditions.
