Abstract This thesis presents a new relay model for the transformer differential protection. The thesis focuses on some operating condition which cause differential relay mal-function. It proposed a self-adaptive differential characteristic that help to avoid such relay mal-function. It also introduced a transformer Internal fault model to investigate the performance of the proposed relay model during internal faults using PSCAD/EMTDC software program |
