Abstract

This paper presents a simplified Busbar Protection Scheme for HT/EHT Busbars. Presently for Busbar Protection scheme, Busbar current Differential Relays are being widely used around the world. In this Paper, we evolve that the cost-effective Busbar protection is being achieved by the back-control method of the Incomer’s Highset OC & EF trip function by the outgoing feeders’ OC & EF start function. The objectives are achieving Busbar protection by utilizing the outgoing and incomer feeders’ OC & EF Relays itself, to eliminate the CT, DC and Tripping circuits complexity that exists in the conventional Busbar protection scheme, to achieve the reduction in cost and control room area for Busbar Protection scheme, to make easiness in future expansion of bays in respect of Busbar protection. © 2022 Elsevier B.V., All rights reserved.
