摘要：

The possibility of non-operation for internal faults of second harmonic restraint differential protection of transformers is studied in this paper. This problem is analyzed using three algorithms for a larger number of faults and energization of a transformer. The sample data used is based on on-line tests of a laboratory transformer. Modified schemes to improve operation for internal faults are presented.
