Answer / harsha
power means
voltage*current
power t/f(1-phase,3-phase)is designed to change amplitude
of high frequency pulses by the turns ratio and provide
isolation b/wcircuits
distribution transformer is used to change the voltage
levels ex:high to low&low to high
(step up t/f&step down t?f)

Answer / raj
Power transformers are used for transmission as a step up
devices so that the I2r loss can be minimized for a given
power flow.These transformers are designed to utilize the
core to maximum and will operate very much near to the knee
point of B-H curve(slightly above the knee point value).This
brings down the mass of the core enormously.Naturally these
transformers have the matched iron losses and copper losses
at peak load (i.e the maximum efficiency point where both
the losses match).
Distribution transformers obviously cannot be designed like
this.Hence the all-day-efficiency comes into picture while
designing it.It depends on the typical load cycle for which
it has to supply.Definitely Core design will be done to take
care of peak load and as well as all-day-efficiency.It is a
bargain between these two points.

Answer / narendra verma
in short we can say that power trans belongs to the voltae
ratings above the 33kv and distribution trans are for low
voltages.....
it is also right that the size of the power trans is much-
much bigger then the distribution trans, that is all bcoz
of the rating and the operating voltage.........

Answer / sunshine
Power transformer is used with Current transformer.
There is only one power transformer at generating station only, but many current transformers.
This is to check faults and measurement purpose.
where as distribution transformer are every where for efficient power transfer.

Answer / manish mathuriya
above 200 kVA power T/F
below 200 kVA distribution T/F
greater the power ratting higher the efficiency.

Answer / anand
Powr transformer are used in transmission network to step
up/down voltage viz 440/220KV, 220/110 KV,33/11 KV and
generaly of capacity 1 MVA or more.
Distibution transformer as name implies are used in
distribution network and steps down voltage to.433 KV &
normally of capacity less than 1 MVA viz 11/.433
KV,33/.433KV

I have tow 200 KVA UPS, both are in parallel mode.My question is that, both are running on battery when power fail, if one of them fail (Eg rectifire fails or some other reason), at thet time reverse power will come to faild ups if it comes then it will harm to failed ups or not? if not then how it protects to faied ups????????????????
