Answer / prasanna d nerkar

Transformers are classified as two categories: power
transformers and distribution transformers.
Power transformers are used in transmission network of
higher voltages, deployed for step-up and step down
transformer application (400 kV, 200 kV, 110 kV, 66 kV,
33kV)
Distribution transformers are used for lower voltage
distribution networks as a means to end user connectivity.
(11kV, 6.6 kV, 3.3 kV, 440V, 230V)

Answer / ashok reddy, r

power transformer generally operated at full load. Hence,
it is designed such that copper losses are minimal.
however, a distribution transformer is always online and
operated at loads less than full load for most of time.
Hence, it is designed such that core losses are minimal.

Answer / hardik vyas

the main difference between power and distribution
transformer is, distribution transf. is designed for max.
efficiency at 60% to 70% load as normally doesnt operate at
full load all the time. Its load depends on distribution
demand. Where as power transf. is designed for max. effi.
at 100% load as it always runs at 100% load being near to
generating station.

Answer / pundlik m wanwe

as per the design is concerned 1)the flux density is higher
than the distributin transformer.
2) power transformers are normally having higher voltage
(KV)and capacities (KVA).
3) Power transformer are so designed that they will have
Max. efficency at rated full load and the distribution
transformers will have max. efficency at 50% loading.

Answer / muhammad shoaib

power transformers are designed so that copper losses be
minimum and distribution transformer are so designed so that
iron losses be minimum.

Answer / uma sanker dwivedi

POWER TRANSFORMERS ARE INTEGRAL PART OF TRANSMISSION SYSTEM
HOWEVER DISTRIBUTION TRANSFORMER ARE PART OF DISTRIBUTION
SYSTEM.

Answer / kaleem

Both power and distribution transformers are used for T&D
applications (transmission & distribution). The difference
between power and distribution transformers refers to size
& input voltage. Distribution transformers vary between 25
kVA and 10 MVA, with input voltage between 1 and 36 kV.
Power transformers are typically units from 5 to 500 MVA,
with input voltage above 36 kV.

Answer / shvetang dave

Power Transformer are used for step up purpose from
trnasmission station to distribution station. Normally from
750 KV to 11 KV it is to be used. It is design for only I2R
losses b'coz Iron losses are constant b'coz it is operated
for constant application.

Whereas distribution Transformers are used for step down
purposes b'cos it is used for distribution purposes. It can
be used for Factory's required power as well as in society
it can be used for home's use. It can be used for 11 kv to
230 Voltage purposes. It can be Design for iron losses
b'coz It is operated for 70 to 80% operation so I2R losses
are not so much important

Answer / poly20

Those transformers installed at the sending or receiving end of long high-voltage transmission lines are the power transformers.

Answer / latika

Distribution transformers have LV side with 440/220V which
distributes the power to promises, shops, industries and
offices. So it is conventionally called distribution
transformer. 440V/ 220V are the Indian Standard dist.
voltage with 50HZ Freq. So in India transformer with LV side
having output of 440/220V is generaly called distribution
transformer. All others are power Transformer.
