Answer Posted / eng.tha&
in transmission We need to convert the Generating voltage
to Transmission voltage
because generating voltage has low voltage but high current
and we use a step up transformer after Generating unit to convert to high voltage and low current.
By reducing the current we get to minimize the losses at lines
since P=I^*R (R=Resistance of transmission line)
and the second benefit of decreasing the current by reducing the cross sectional area of cable (high current need high cross sectional area )i.e= reduce the cost
finally
at the Receiving end
we used a step down transformer to convert to low voltage and high current
we transmission electricity from on place to another with less losses and efficient method
