| Abstract: | Transformer longitudinal differential protection is the main protection of transformer. Contain non periodic components of a lot of transformer magnetizing inrush current, With enhanced velocity saturation differential relay con- verter, can effectively avoid the inrush current. The design analysis of DCD-2 typerelay function and working principle are based on, setting calculation of transformer differential protection. |
