Answer Posted / naresh kumar
Reasons:
1)to reduce the conductor size of the feeder.... i.e, by
increasing the voltage levels the current level decreases to
maintain constant power.. the feeder design depends on the
current levels so lesser currents lesser will be the cross
section...
2)by increasing the voltage levels the current levels
decreases so the i^2 R losses decreases and the transmission
efficiency increases.
