Step up transformer means that the output electric voltage is higher than the input voltage. A transformer that increases electric voltage from primary to secondary is called a step up transformer. The step up transformer's definition also refers that more secondary winding turns than primary turns. In the contrast, a transformer that designed to do just the opposite is called a set down transformer.
This kind of transformer "steps up" the voltage applied to it. For instance, a step up transformer is needed to use a 220v product in a country with a 110v supply.
step up transformer are one of the really common and vital electrical tools used in power transmission and modification. step up transformer usually the first major transformer in a transmission system and are often used in various forms throughout the system.
step up transformer is based on the same formulas that other transformers are, but the key element is that they convert voltages to higher volumes while reducing amperage and effects of resistance. This makes step up transformer ideal in long-distance power transmission use; by stepping up voltage and reducing amperage little energy is lost to resistance.
Mostly step up transformers located near power plants. They are house-sized units designed to handle megawatts of power. The step up transformer takes the 12,000 to 25,000 volts coming out of the generators and increases it to 138,000 or as much as 765,000 volts.
We need get more knowledge about the step up transformer, so we can work with it perfectly.
