For transmitting the power generating substation transformer should connect delta star for step up at high voltage also getting ground wire for reducing third harmonic current in transmission line.

Answer / bhramit agarwal

bcoz ie is in star per phase voltage is 1/3^1/2 times the line voltage.so overall voltage decreases.and loss in a line is decreased.

Answer / suresh apgenco

to provide path for third harmonic currents and as line
voltage is equal to phase voltage, size of the conductor
will reduce.
