A substation transformer is a vital component of power systems, designed for use in both large and small three-phase transmission and distribution systems. These transformers are strategically placed within substations, whether indoor or outdoor, typically on concrete bases that are carefully planned during the project's early stages by power engineers.

Installation Location: Substation transformers are commonly situated indoors or outdoors, with their placement determined by project requirements and power engineering specifications.
Cable Connections: High-voltage and low-voltage cables are connected to the substation transformer through bushings, either at the side end or the top. These connections allow current to flow into other substation equipment, such as control cabinets, for further distribution and control.
Oil-Immersed: Substation transformers are typically oil-immersed and can use various types of insulating oil, including mineral oil, vegetable oil, or siliceous transformer oil. This design ensures efficient cooling and insulation.
Voltage Class: Substation transformers adhere to specific voltage classes, with primary voltages typically ranging from a minimum of 2.4 kV to a maximum of 69 kV. Secondary voltages can vary from a minimum of 0.6 kV to a maximum of 35 kV, following IEEE standards.

Utility Substation Transformers: These transformers are used by industrial power distribution companies and provide output voltage for private individual consumers. They can output both single-phase and three-phase AC current, with common voltage ratings like 120V, 240V, and 400V. Utility substations may be located in urban or rural areas, with urban substations often enclosed within protective walls.

Personal Substation Transformers: These transformers are used for personal consumption by end-users, such as schools, hospitals, and restaurants. They are typically connected to medium and low-voltage grids.
