Abstract:  For successful transformer differential protection employment, correct discrimination betweeninrush current and fault current is essential. It is one of the main focuses of research and one of the mainchallenges for transformer protection. In this paper, a discrimination method based on utilizing chromaticmonitoring of the box dimension algorithm outcome curve for transformer differential current in time-domainanalysis is proposed.The x-L chromatic mapping is employed for general detection of fault cases, while the x-y chromatic mappingresult is used for distinguishing inrush current from the fault current cycles.The preliminary results show that the proposed method can effectively provide correct discrimination of thecurrent type within quite a short time and thus help in providing efficient decision-making supportiveprotection tool This email address is being protected from spambots.
