What are the basic differences between power and
distribution transformer? Vajra Transpower is a
reputed transformer manufacturing company, which
manufactures both powers as well as distribution
type transformers. The working principle and
applications of both types of transformers are
different. As one of the leading power
transformer manufacturers in Hyderabad and a
distribution transformer manufacturer, Vajra
Transpower find out the basic difference between
these two transformers. Power transformers are
basically used in transmission purposes for high
voltages. The step-down and step-up transformer
manufacturers use this type of transformers and
step-down step-up applications. Distribution
transformers are used for low voltage
distribution to end-user connectivity. It is
generally rated less than 200MVA. Transformer
size For heavy load transmission, transformer
manufacturers build power transformers. Its high
voltage is more than 33KV and 100 efficiency. If
we compare its size, then it has a big size than
the distribution transformer, used in the
transmission substation and generating station.
Its insulation level is also very high, whereas
distribution transformers are used for the
distribution of electrical energy at a very low
voltage level. Its voltage level is less than
33KV for industrial purposes and 440v-220v for
domestic purposes. The electrical transformers
manufacturers use this type of transformers for
low-efficiency requirements. It is small in
size, easy to install, having low magnetic losses
it is not fully loaded. Losses The power
transformer manufacturers build the power
transformers for transmission network, thats
why they dont connect to the consumers directly,
so load fluctuations are very less. These types
of transformers are working 24hours a day, so
iron losses and copper losses take place
throughout the day.

The average loads are near to the full loaded or
these full loaded transformers are manufactured
by the dry type transformer manufacturer in such
a way that at full load condition, they can be
100 efficient. These types of transformers are
very independent of time. Only the basis of
power, efficiency can be calculated. In the
distribution network, distribution transformers
are manufactured by distribution transformer
manufacturers and used, which are directly
connected to the clients. In this caseload,
fluctuations are very high. All the time, these
transformers are not fully loaded so only iron
losses take place 24hours throughout the day and
copper loss takes place based upon the load
cycle. In this case, average loads are near about
75 of the full load and these types of
transformers are designed in such a way that
maximum efficiency occurs at nearly 75 of full
load. Efficiency The actual difference between
distribution and power transformer is that the
distribution transformer manufacturer in
hyderabad manufactures the transformer-based
upon the 60 to 70 efficiency as normally it
doesnt operate at full load all the time. Its
load depends upon the demand for
distribution. Whereas power transformers are
manufactured by the power transformer
manufacturers having the maximum efficiency at
100 load since it always runs at 100 load
being near to generating station. Distribution
transformers are used where the voltage tends to
be lower. Most of the distribution systems tend
to involve in clusters of loads fed from
distribution transformers. Contact Us Website
