This device is very common used in electronic/electrical industry in the world.Start from small transformer for electronic equipment until big transformer for High voltage power transmission.Transformer is important device in our life every day.
The main purpose of voltage Transformer is a changing or “transform” the value of voltage ( single or three phase ) .
It can step up the voltage value ; example : 110VAC step up to 240VAC ( For power supply usage ) or 11 kVAC step up to 33 kVAC ( for power transmission).
It also can step down the voltage value ; example : 240 VAC step down to 24 VAC ( For rectifier power supply) or 11 kVAC step down to 415 VAC ( For Consumer power supply ). read more
