A transformer substation is a part of the electrical installation that includes the terminations of the transmission or distribution lines and switchgear. It contains one or more transformers as the central part. The substation also typically includes all the necessary devices for control and protection of electricity and itself.
Transformer substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Before being used, electric power may flow through several transformer substations at different voltage levels. A transformer substation includes transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.

Classification Of Transformer Stations According To The Purpose Of Using
a. Outdoor transformer station
Outdoor substations are intermediate transformer stations with large capacity, transformers and station equipment with quite large size, so the space to build the substation needs a large area. However, when building these transformer stations outdoors, it causes a number of disadvantages that are visible first of all, causing loss of aesthetics, not suitable for urban areas serving mainly in factories. Industrial factories or production areas need large capacity of electricity.
b. Indoor transformer station
The indoor substation is the most commonly used station today because it is suitable for construction and power supply in densely populated urban areas without affecting the aesthetics with suitable size. Can be placed in a closed house to ensure safety for the people around. There are 2 types of indoor substations including closed stations and Gis stations.
