Answer / mohammed sohail

at the point of application . the voltage rating of
equipment are different . and each equipment is designed to
operate safely at that voltage ratings . so inorder to reach
the optimum voltage, Transformers are used

Answer / nithi

Generally, power is generated in the voltage level of 11kv
(upto 15kv).
For the same power transaction from power station
to the load center, if we increase the system voltage,
correspondingly the magnitude of the current will be
reduced. The reduction in the current level has the
following advantages.
1.Reduction in the transmission line voltage drop.
2.Reduction in the size of the conductor.
3.Power loss is reduced.
4.Efficiency and the voltage profile of the system are
improved.
