Power transformers perform a pivotal role in a power system network in ensuring reliable power supply to electricity consumers. This paper contributes the concept about different types of transformer protection so that will be more helpful for investigating the protection system of the transformer. In this Paper, an effort is made to put together developments in the protection of the transformer. Efforts have been made to cover all the techniques and philosophies used to that end. The article includes the most recent techniques and traditional techniques of the transformer. There are many important parts installed in the transformer which is very costly so these have to be safe in an abnormal condition. Transformer performs a great job in the power system to change voltage and current level so proper protection for the transformer is important to maintain reliability in the system. Usually, a well-designed transformer protection system provides a great life without any uninterrupted power supply. To increase life, efficiency, overall performance then reduces stress on the transformer is the only way so this protection system help here to observe those things properly.
