| Abstract: | When putting the new transformers of the Nanjing BASF Petrochemical plant's substation into operation, overcurrent protection maloperations of the incoming line switch occurred repeatedly. The sympathetic current model was used to explain the phenomenon, and countermeasures for preventing the overcurrent protection maloperation under such condition are put forward. |
