I. Why is It so Important?Electricity needs to take a long "journey" from power plants (such as hydropower stations and wind farms) to your home. In this process, the transformer plays an indispensable role:"Boost voltage" for operation to reduce losses: The electricity voltage generated by power pl

In modern life, electricity is like an invisible bond, closely connecting all aspects of our lives. From being awakened by an electronic alarm clock in the early morning to falling asleep peacefully under the light at night, the presence of electricity is everywhere. Behind the scenes of ensuring a

I. Core functions and technical principles Transformer as the transmission of electrical energy “heart equipment”, through the principle of electromagnetic induction to realize the alternating current voltage rise and fall, to support the efficient and safe operation of the power grid. Its core indi

1. Core mission: to change the voltage of an alternating currentCore function: The primary function of a transformer is to raise or lower the voltage of an alternating current.Why need to change the voltage?Long-distance power transmission (voltage): power from the power plant (such as thermal power
