A substation transformer is static electrical equipment used in a power system. It relies on electromagnetic induction to convert alternating current energy of one voltage and current into another voltage and current of the same frequency.

The substation transformer is the main equipment of the substation, which is divided into the two-winding transformer, three-winding transformer, and self-disaster transformer, that is, the high-voltage and low-voltage phases share one winding and ahead is drawn from the middle of the high-voltage winding as the outlet of the low-voltage winding. The voltage level is proportional to the number of winding turns, and the current is inversely proportional to the number of winding turns.

Voltage Transformation:

The primary function of substation transformers is to transform voltage levels. They can step up voltage for long-distance transmission or step down voltage for distribution to consumers.
Types of Substation Transformers:

Power Transformers: These transformers are used for bulk power transmission and are typically located at the generating stations and major substations.
Distribution Transformers: These transformers are deployed in distribution networks to step down voltage for supply to homes, businesses, and other end-users.
Step-Up and Step-Down Transformers:

Step-Up Transformers: Increase the voltage from the generator output to the transmission voltage level.
Step-Down Transformers: Decrease the voltage to distribution levels suitable for supplying power to homes and businesses.
Three-Phase Configuration:

Most substation transformers are designed to work with three-phase electrical systems, providing a balanced and efficient power distribution solution.
Cooling Systems:

Transformers generate heat during operation, and efficient cooling is essential. Cooling systems can include natural convection, forced air, or oil circulation methods to dissipate heat and maintain optimal operating temperatures.
Oil-Immersed Transformers:

Many substation transformers are oil-immersed, where the transformer core and windings are immersed in a cooling and insulating oil. The oil provides both insulation and aids in dissipating heat.
Dry-Type Transformers:

In some cases, substations may use dry-type transformers, where the core and windings are not immersed in oil. Dry-type transformers are often chosen for environmental or safety reasons.
