About Trance

A transformer is a static induction device that converts AC voltage or current into any value using electromagnetic induction. A device that steps down voltage is generally called a transformer, and a device that steps up voltage is called a booster. A booster is also a transformer, just by changing the name. It consists of an iron core and windings, and basically has a structure in which two windings are wound around an annular iron core. The winding connected to the power supply is called the primary winding, and the winding connected to the load side is called the secondary winding. Due to the characteristics of transformers, heat is generated due to iron loss and winding resistance during use, so energy is consumed as heat and output decreases. not. Transformers with a capacity of 50 kVA or less are called small, those with a capacity of 500 kVA or less are called medium (medium capacity), and those over 500 kVA are called large (large capacity). Also, depending on the voltage used, it is called low voltage / high voltage / extra high voltage / extra high voltage (extra high voltage).
