This study presents a new current transformer (CT) saturation detection and compensation algorithm. The proposed algorithm depends on a saturation detection index (Dn) which is derived by using the derivatives of the current signals and Newton's backward difference formulae. The calculated index is continuously compared with an adaptive threshold (Th) to estimate the start and the end point of CT...
The protection of busbar demands high integrity and high speed relaying scheme. This paper presents a new differential relaying scheme for the protection of busbar. The proposed scheme depends on the difference of the value of incoming and outgoing line currents of the respective phase at a particular bus. The proposed scheme has been tested extensively using the PSCAD/EMTDC software package with...
