Objectives	To report on the practicalities reliability and potential benefits of implementing alternative non conventional current sensors. Expected Benefits: To identify potential of implementing non conventional current sensors across the transmission network.
Abstract	This R&D Project aims : To evaluate the practicability, reliability and benefits of implementing alternative non conventional current sensors (i.e. Rogowski coil) based differential unit protection for Cable systems (i.e. Cable only and Cable & OHL hybrid installations) over conventional Current Transformer (CT) based protection. To carry out the preliminary evaluation a pilot installation is recommended on Pitsmoor-Wincobank cable circuit on April 2012 as monitoring unit. To determine the systems suitability to be utilised as Emergency Return to Service (ERTS) system. This will help to formulate a technical and operational knowledge base for Non Conventional Instrument Transformer (NCIT) protection systems which could lead to evaluation of future technical and procurement strategy to deploy as replacement and/or new Cable system protection.
