See transformer mainly used for step up purpose are of the
detal-star connection,the advantage is that in the seconary
for step up the insulation req is lessa s the voltage is
57.7 of actual vaue in secondary.So consdier ur question
now? is it advantageous.Transformer designs are done not
merely on load,but the winding
insulation,oil,insulation,cooling,etc are also important.

While performing stability test of differintial cts how to know the voltage and current on both side of the transformer?
