1. During operation, if it is found that the load of the transformer reaches 90% or more of the rated value of the corresponding voltage regulating tap, it should be reported to the dispatcher immediately and kept in good records. 2. According to the allowable overload condition of the transformer, make timely records and send a dedicated person to monitor the load of the main transformer, the upper oil temperature and the winding temperature. 3. Conduct special inspections of transformers in accordance with the requirements and projects of special inspections of transformers. 4. During overload period, all coolers of the transformer should be put into operation. 5. After the overload is over, it should be reported to the dispatcher in time and the overload end time should be recorded.
There are clear provisions on overload operation in the transformer operating procedures and transformer instructions. In actual operation, pay close attention to the operating status of the transformer and take measures to reduce the load or transfer the load to ensure that there are no problems with the equipment.
