Let me talk about the specific functions of power transformers whitch decide why transformers are used in transformission and distribution system:

Long-distance power transmission: When we want to transmit electricity over long distances, it is definitely not possible to use low-voltage current, because low-voltage current in the circuit is not only slow, but also has higher heat loss due to the slow speed and resistance in the circuit. In order to avoid this result, we can use power transformers (step-up transformers) to increase the voltage to reduce the current on the transmission line, thereby reducing the energy loss caused by resistance during transmission. By using step-up transformers, we can enable electricity to be efficiently transmitted from power plants to power consumption areas far away from the power source. (Regarding the issue of enameled copper wire and enameled aluminum wire, Yawei transformers are also trustworthy)

Adapt to load requirements: Different electrical equipment and systems have different voltage requirements. Power transformers can convert high-voltage electrical energy into low-voltage electrical energy (step-down transformers) suitable for specific equipment or systems to ensure the normal operation of the equipment. For example, low-voltage equipment and high-voltage poles used in daily life are good reference objects: high-voltage poles are part of the power system, and their voltage is usually higher than the voltage of our daily electrical equipment due to transmission requirements, but our daily electrical equipment does not need such a high voltage. So we need to step down the current. The act of distributing the electricity from the high-voltage transmission line into the transformer and then stepping it down is also called distributing electricity. In the distribution network system, the transformer can convert the high-voltage electricity from the main line (usually from the high-voltage pole) into low-voltage electricity suitable for home and industrial use. By using step-down power transformers, we can ensure the safe use of electricity resources by end users. (Yawei Transformer can provide free, professional power engineering consulting services)

Improve system stability: In the power system, power transportation usually has voltage fluctuations and other situations. Appropriate voltage conversion through transformers can improve the stability of the power system and reduce the risk of equipment damage or unstable operation caused by voltage fluctuations. Achieve improved power quality because proper voltage conversion can reduce harmonics and other power quality issues, thereby improving the overall performance of the power system.
