The main power transformer is a device used to change the AC voltage using electromagnetic induction means. It has a main member or the primary coil, the secondary coil, and a core. The function of this transformer includes voltage conversion, current conversion, impedance transformation, isolation, and regulation.
A main power transformer is a critical component in power generation and distribution. It is an electrical device that is used to transfer electrical energy from one circuit to another through electromagnetic induction. They are designed to handle high voltages and currents and are used to step up or step down the voltage of electricity to the desired level. Power transformers can be used in a variety of applications, including substations, solar projects, and other energy-intensive operations.

types of main power transformers
There are several types of main power transformers based on their application and construction. Here are some of the most common types of main power transformers:
Three-Phase Transformers: This is the most commonly used type of main power transformer, designed to transform high voltage electrical power from the primary winding to a lower voltage in the secondary winding. The three-phase transformer consists of three single-phase transformers assembled together.
Autotransformers: An autotransformer is a type of transformer that has a single winding with two end terminals, used to step up or down the voltage in a single circuit. In an autotransformer, a part of the winding is used for both primary and secondary voltage transformation.
Distribution Transformers: Distribution transformers are used to transform high voltage electricity from the transmission lines to a lower voltage, suitable for distribution to end-users.
Power Transformers: Power transformers are used in substations to step up or step down the voltage level of power for transmission or distribution.
Instrument Transformers: Instrument transformers, such as current and voltage transformers, are used to measure the high-voltage and high-current power flow in the electrical network.
Rectifier Transformers: Rectifier transformers are used in the electrical power industry to supply power to the DC circuits of large industrial operations, such as electrolysis plants, aluminum smelters, and steel mills.
