| Abstract: | According to the technical codes and the countermeasures of the state grid, this paper analyzed the influence on transformer protection when arc-suppression coil is installed at the neutral point of the main transformer. All kinds of system failures related are discussed in this paper, a comparison with arc-suppression coil installed at the zigzag grounding transformer is also provided. On the basis of the analysis above, a scheme of transformer protection for this kind of project is put forward. |
| Keywords: | main transformer neutral point zigzag grounding transformer arc-suppression coil electrical protection. |
