What is Power Transformer ？
Power transformer is a kind of static electrical equipment, which is used to change a certain value of AC voltage (current) into another or several different values of voltage (current) with the same frequency.
How does Power Transformer work ？
Power transformer is a kind of static electrical equipment, which is used to change a certain value of AC voltage (current) into another or several different values of voltage (current) with the same frequency. When the primary winding is connected with alternating current, alternating magnetic flux will be generated. The alternating magnetic flux will induce the alternating electromotive force in the secondary winding through the magnetic conduction of iron core. The secondary induction electromotive force is related to the number of turns in the primary and secondary windings, that is, the voltage is directly proportional to the number of turns.
