| Abstract: |
| The analysis of an interturn fault about one percentage turns is introduced and a calculating formula for estimating the interturn fault current of the transformer is derived.According to the calculation result and features of low percentage interturn fault,the general characteristic selection for percentage differential relay of transformer is suggested. |
| Key words: Transformer,Interturn faults,differential protection |
