Introduction: This project is investigating the development of Optical Current Transformer (CT) prototype in conjunction with Manchester University. The product is an innovative new CT designed for use on the high voltage network.

Objectives: The device would be a replacement for traditional iron cored CTs. There are devices on the market that are similar to this at present however they have not gained acceptance within the industry as they have severe restrictions on operation. This project will aim to remove these issues and create a device that will provide enhanced flexibility to the transmission system.
