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.

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.

Generally speaking, a distribution transformer is a type of electrical transformer that used to step down high voltage electricity from the distribution system to a lower voltage which is more suitable for use in homes, businesses, and industries.

Some key points about what is distribution transformer is as follows:

Function: Brifly, the distribution transformers is the equipments convert high-voltage electricity (typically from 11kV to 33kV) to lower voltages (such as 230V or 400V) for consumption.

Location: The distribution transformers are usually located near the end-users(pad mounted transfor), either on utility poles(pole mounted transformer) or in substations.

Construction: They consist of primary and secondary windings wrapped around a core.The core usually made of laminated silicon steel to minimize energy losses.Moreover, the copper or aluminum are chosen to be the winding materials.

Cooling: Distribution transformers can be air-cooled or oil-cooled to dissipate heat which generated during operation.The cooling method is closely related to the transformer's temperature rise.

Efficiency: The distribution transformers are often required to designed to operate efficiently under varying load conditions, ensuring minimal energy loss.

Types: There are several types, including pole mounted transformers , pad mounted transformers and underground transformers which are suitable for their different installation environments.So, if we want to choose the transformer that suitable for us, the installation environment is the priority.

Distribution transformers play a crucial role in the electrical grid by ensuring that electricity is delivered safely and efficiently to end users.

Power transformers and distribution transformers are both essential components in the power system. They are both transformers and can perform voltage conversion, so their uses and working voltage levels are the main aspects that distinguish them.

Different uses: Power transformers are mainly used for voltage boosting in the transmission network to achieve long-distance power transmission. Distribution transformers are mainly used to transmit electricity from the transmission network to end users (homes, businesses, etc.). In short, power transformers have large capacity and high power characteristics, which meet the functions of transformers in the power system for voltage boosting and voltage reduction distribution. However, considering the cost-effectiveness, power transformers are mainly used at the primary end, while distribution transformers have a lower design capacity and are more used for voltage distribution of end users.

Different voltage levels: Power transformers usually work at the high-voltage end (above 33 kV). In comparison, the working voltage of distribution transformers is usually below 33kv.

In summary, power transformers and distribution transformers appear due to their design purposes and functional characteristics.
