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)

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.

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 / 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.

what is the basic need of domestic loads 1- voltage 2- current
Is there any specialised book to refer about fault level calculation both in MV and LV side??
Why the standard of ambient teperature mentioned as 40 degree celcius in machines.
what is the need of reactor in between the transmission line?..like powergrid like that..
If there is 25 hp motor,which type of starters we can us? why?
How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.
what is the best way to start a 15 KW motor for pump star-delta or direct on line ? and from how many KW i must use direct on line ?
How shall i select the value of capacitor or inductor in a system?
If the capacitor feeder is switched ON without any load, is there any display in the ammeter at the incomer?
How does a tertiary winding filter harmonic(espcially 3rd one) from entering into load system?
If AVR fails in DG set what will be the affect?
