Step down transformer & Step up transformer calculator:
The transformers are being classified based on the output voltage levels and they are step-down transformer and step-up transformer.
Step-up transformer:
If the output voltage is greater than the input voltage, then such transformers are called a step-up transformer.
i.e Vp input voltage in volts and Vs output voltage in volts, if Vs > Vs then such transformers are called a step-up transformer.
Output voltage > Input Voltage
Step Down Transformer:
The transformer which output voltage is lesser than the input voltage is called step down transformer.
Typically,
Vp > Vs
Input Voltage > Output Voltage
The difference between these two voltages always maintains an integer ratio, It is called voltage ratio.
How to identify a transformer?
Generally, if the transformer is mentioned by 11kV/415V means, it is called step-up transformer, the input will be given as 11kV and the output will be connected to 415V.
At the same time, the transformer is mentioned by 22kV/220kV means, it is called a step-up transformer. The input will be 22kV and the output will be 220kV.
Another transformer is called the ideal transformer whose input voltage is equal to the output voltage.
