1.We need Transformer to step up and step down voltage
level w/o having much loss.
2.Step up voltage was used to Transmit the power to very
long distance w/o higher transmission loss.
3. Because of Static device it operating effiecincy is 98%
compare to any electrical device.
4. Easy control & voltage adjustment.
