Impedance test is known as short circuit test,from this
test we get the full load copper loss.In this test low
voltage winding is always short circuited and
measurementare should make at the high voltage side.

how the transmission voltage ranges are decided like 11kV,33kV,66kV,132kV,220kV,400kV,725kV.... why not choose the transmission line voltage as 23kV,164kV,440kV?? what's the reason??
