What is the substation transformer?

Substations play an important role in handling the electrical power consumed from generation to distribution. They also ensure that power is transformed and converted to suit different electrical needs. Transformers are used for various functions to accomplish that efficiently.The substation transformer is the heart of the electrical substation. Substation transformers are designed for the installation of large or small three-phase transmission and distribution systems. Substation transformers are installed indoors or outdoors on concrete pads, high and low voltage cables through closed side wall installation bushing or through the cover, and some are through the side wall installation bushing into the operation room.
Substation transformers can be divided into distribution substation transformers and station-type transformers：
Distribution substation transformer: A distribution transformer designed for installation in a station or substation. It have cover-mounted primary and secondary bushings and can be provided with load tap changers (OLTC).
Station-type transformer: A transformer designed for installation in a station or substation. Station transformers are typically located in power substations, which are facilities that control and distribute electricity.
