PURPOSE: A method for replacing a single or three phase pole transformer is provided to prevent the inconvenience of a consumer and economic loss by rapidly replacing a pole transformer in an uninterruptible state. CONSTITUTION: A high voltage bypass cable(4) is connected to a bushing of a single phase solid insulated switchgear(6). A low voltage bypass cable is connected to a low voltage bushing of a single phase transformer(9). A low voltage bypass cable is connected to a low voltage bus bar(12) of the conventional pole transformer. The low voltage bus bar of the conventional pole transformer is separated. A new pole transformer is installed. The low voltage bus bar is connected to the low voltage bushing of the new pole transformer. The high voltage bypass cable is removed. The low bypass cable is separated from the low voltage bus bar of the new pole transformer. |
