What is function of transformer?

The main functions of power transformers include:
Voltage conversion: Power transformers meet the needs of different power systems by stepping up or down. Compared with low-voltage current, high-voltage current has the characteristics of low loss and fast transmission speed in the same transmission medium. Therefore, in long-distance transmission circuits, we always use step-up transformers to increase the current voltage, and then send it to the power consumption area, and then step down the voltage through step-down transformers, and then the distribution lines supply power to nearby lines.
Isolation: Due to its internal insulation characteristics, power transformers determine that it can provide electrical isolation between different parts of the power system, thereby improving the safety of the entire power system and reducing the risk of electrical failures.
Efficiency: Power transformers are designed to achieve high efficiency and minimize energy losses during voltage conversion (click to learn why is power conserved in transformers).
Structure: The two main structures of power transformers are the core (usually made of laminated silicon steel sheets) and the winding (made of copper or aluminum). The core is responsible for magnetic flux in the power transformer, while the winding is responsible for induced voltage. Compared with aluminum, copper has lower current loss, but due to price reasons, transformers with aluminum windings still occupy a large share in the market.
Application: Power transformers are used in various applications, including substations, industrial plants, and power generation facilities. Due to the rise of virtual currencies such as Bitcoin, the role of power transformers in the "mining industry" cannot be ignored. At the same time, the application and demand for power transformers in industries such as artificial intelligence are also expanding.

In short, a power transformer is a static power conversion device that is critical to the reliable distribution and transmission of electrical energy in power systems.
