Electricity is a form of energy and occurs in nature. It was not invented. The
discovery of electricity happened some six hundred years ago. Some give credit
to Benjamin Franklin, who helped to establish the connection between lightning
and electricity.
It is one of those discoveries that have changed the daily life of everybody on the
Planet. The point is, without electricity, modern day life will simply come to a
stop. In fact, the advancement of a country is measured by the index per capita
consumption of electricity – more it is more advanced the country is.
So the generation and distribution of electricity is necessary to fulfill the need of
people all over the world.

 Electricity generation is the process of generating electrical power from
different form of energy. The fundamental principles of electrical generation
were discovered during 1820s and early 1830s by the British scientist Michael
Faraday.
 Power is produced in various kinds of power plants and electric power
generating stations. A generating station essentially employs a prime mover
coupled to an alternator for the production of electric power.
 Generation, transmission and distribution of electric power in our country is
carried out as 3-phase system at 50 Hz.

4. TYPES OF POWER GENERATING
STATIONS
 THERMAL POWER STATION
 HYDROELECTRIC POWER STATION
 NUCLEAR POWER STATION

 In a thermal power plant coal is burnt to produce high temperature and high
pressure steam in a boiler. The steam is passed through a steam turbine to produce
rotational motion. The generator, mechanically coupled to the turbine, thus rotates
producing electricity.
 The fuel(coal) for this power plant is quite cheap and the installation cost for this
power plant is less compare to other. But its pollutes the atmosphere due to the
production of large amount of smoke and its running cost is higher compared to
hydroelectric plant

 This generating station utilises the potential energy of water at a high level
for the generation of electric energy.
 It requires no fuel as it fully depends on water, it is quite neat and clean as no
smoke or ash are produced, and requires very small running charges. But the
installing cost of dam is too high and requires skilled and experienced hands
to build the dam.

7. N U C L E A R P O W E R S T A T I O N
 In this generating station nuclear energy, which is produce by nuclear fission
of 𝑈235, is converted into electric energy.
 It produce a bulk electric power from a very small amount of fuel and hence
its running charge is small. But the fuel is expensive and hard to recover and
it cause danger amount of radioactive pollution

8. DISTRIBUTION OF ELECTRIC POWER
 The huge amount of power generated in a power station (hundreds of MW)
which is transported over a long distance (hundreds of kilometres) with the
help of transmission line and transmission towers, then it is distributed to
different industry and for domestic purpose.
 The electric power is transmitted by overhead line or by under ground cable.
 The generated power is step up by the transformer and transmitted to the
substation, which is there step down and distributed to the consumer.

10. VARIOUS CONPONENT OF REQUIRED IN
TRANSMISSION AND DISTRIBUTION OF CURRENT
There are various component are required for transmission and distribution of current
like,
 Transmission Towers
 Cable
 Transformer
 Insulator
