| Abstract: | If master transformer of 220 kV substation adopts sleeve-type current transformer as failure protection,misoperation or refuse operation may appear in bus failure protection when fault takes place.This paper profoundly analyzes the problem of this configuration,presents the improving measures of current transformer near 220 kV breaker through the exploration on current circuit connection scheme of master transformer failure protection.The application of these measures in Zhenjiang Power Supply Company has s... |
