How Do Transformers Help In Transmitting
Electricity To End Users?
Have you ever wondered how electricity is brought
into our homes and offices? You know that it is
superbly huge amount of power generated at the
power stations, right? And, you also know that
this huge supply if brought into your homes can
cause serious damage to your appliances and
death too. So then, how does this huge power get
into your homes so safely? It is through a power
system comprising of various step up and step
down transformers. Step up transformers increase
the voltage, while step down transformers
decrease the voltage.
The power lines that you see crisscrossing across
the country carry enormously high voltages of
around 4,00,000 to 7,50,000 volts, delivering
electricity from power plants to homes. But, our
electronics and appliances use only a mere 110 to
250 volts of power. This huge difference in
voltages is only made possible with the help of
transformers. So, you can see what great a role
transformers play to bring us safe electricity
every day! This is the reason the invention of
transformers has proven to be a boon in the power
industry because only after its invention has
become possible the transmission of power and
regulation of voltage. What are step-up and
step-down transformers? Transformers work on a
very simple principle that when fluctuating
electric current flows through a wire, it
generates a magnetic field all around it. The
strength of magnetism is directly
2
related to the size of the electric current. This
means that bigger the current, stronger the
magnetic field. Transformers have a soft iron
core at the center around which copper wire is
wound. Transformers have one primary and one
secondary coil wound around the core. If the
primary coil has more turns than the secondary
coil, the primary coil has higher voltage than
the secondary. This is the functioning of a
step-down transformer that reduces higher voltage
to lower voltage. Reversing the situation, a
step-up transformer can boost a low voltage into
a higher one. How do transformers help to
bring in electricity to end users? Now that you
know what step up and step down transformers are,
let us see how electricity is brought into our
homes from the power station. Electricity is
generated at power plants, which movies through
a complex system known as the grid, comprising
of electricity substations, transformers, and
power lines. The various local grids are
interconnected, forming larger networks that
enhance the coordination and supply of
electricity. There are hundreds of thousands of
miles of high-voltage power lines and millions of
miles of low-voltage power lines across the
country that connect thousands of power plants to
millions of residential and commercial areas for
end users. First, the power is generated in the
utility power plant, which is supplied to the
transmission towers through step-up
transformers. The power then runs through high
voltage transmission lines, travelling through
step-down transformers to reach the substations.
And then, finally, the power is then transformed
to the homes, offices, and factories of end users
through the utility poles that we see on the
streets, having step-down transformers
installed. Apart from these transformers
installed in the power grid system, you would
also need various kinds of transformers
installed within your homes and offices to bring
in safe power supply for your electronic devices
and appliances. For this, you can get in touch
with Miracle Electronics to provide you with the
best kinds of power, medical isolation, EI, UI,
SMPS, audio output, three phase, and toroidal
transformers in India.
