| Abstract: | This paper analyses the overvoltage protection for the neutral poin t of staged insulation transformer. The selection of surge arrester and gap config uration and the coordination into relay protection are covered too. A solution t hat the overvoltage protection for transformer's neutral point is coordinated i nto the relay protection is presented. |
