The transformer is one of the key equipments of the power plant. Its working condition can directly affect the generation capacity of the power plant

which plays a vital role in ensuring the safe and reliable operation of the grid. This paper deeply expounds the main problems existing in the current transformer daily management

and proposes feasible solutions. It points out that strengthening the operation management of transformers from the aspects of formulating a sound management system

improving the professional skills of operation and maintenance personnel

improving emergency response plans

and scientifically managing spare parts is an effective measure to ensure the safe operation of transformers. At the same time

it summarizes the causes of common faults such as transformer overheating

abnormal oil level

and gas protection faults. It is expected to provide reference for the safe operation and daily management of transformers in the future.
