| Abstract: | This paper analyzes the fundamental principle of the fault component based digital differential protection and compares it with the conventional percentage restraint differential protection. Operation criteria for the fault component based differential protection are also discussed and the practical application of this principle in the protection of a generatortransformer unit is described in detail. |
