33kv to 11kv 25000 kva main power transformer Introduction:

The electrical energy generated from power plants must be transmitted over long transmission lines to distant users. To minimize energy losses along the transmission lines, it is necessary to use high voltage or extra high voltage for transmission. However, the voltage produced by power plants is generally limited due to insulation constraints. This necessitates the use of transformers to raise the voltage of electricity generated at the power plants before it is delivered to the power grid. These transformers, designed for voltage elevation, are collectively referred to as step-up transformers.

For end-users, the voltage requirements for various electrical equipment are generally not as high as the transmission voltage. Therefore, transformers are used to lower the high voltage from the power system to match the rated voltage required by various electrical devices. Transformers designed for this purpose are collectively known as step-down transformers.

As such, electrical transformers are the primary electrical devices in the power system used to adjust voltage levels.

From the perspective of the power system, an electrical grid connects many power plants and users, dividing it into a main system and several subsystems. The voltages in different subsystems do not necessarily match, but the main system must operate at a uniform voltage level. This requires transformers of various specifications and capacities to interconnect different systems. Therefore, electrical transformers are indispensable components in the power system.
