Answer / naveen

if distance is very long then we can use hvdc transmission
to reduce the power losses

Answer / minal

we use high voltage transmission under long distance to
reduce power loss.

Answer / sandy

Increase the transmission voltage. Naturally the current
will go down.

Answer / guest

by using step up transformers.

Answer / ravi prakash

POWER LOSS IS ISQUARE R.WHEN WE HAVE TO REDUCE POWER LOSS IN
LONG TRANSMISSION LINE ,WE HAVE TO REDUCE THE CURRENT I. FOR
THE SAME LOAD POWER LOSS CAN BE REDUCED BY INCREASING THE
POWER FACTOR.

Answer / mani

We have to increse the transmission voltage and current can
be reduced so losses will be less

Answer / daher

increase the transmission line cross section to reduces the
resistance .

Answer / comil83

To reduce power loss in HV line u have to reduce current in
trasmission line so voltage will remain as high as
pssible.so u can overcomes from more voltage dropp.For
reducing current in line u have to apply the formula R =
L/A.Where L leanth of conductor and A = circumfanc of
conductor.In ur case lenth of con. is long.so to reduce R u
have to increace A(Thick cable).If R is reduced then losses
of voltage will less but it will also increase your capital
cost of cable transmission.Other way is you can us step up
X'mer at some distance u can improve ur voltage trnsmission
but in this cas also capital cost of ur extra x"mer will
more and also some loss in X"mer is also there.

So u have to select a methode as per ur industrial
aplication.

Answer / ch.phani

to reduce power loss in transmission lines
1)the voltage will have to be increased .but there will be
limitaions for this also
2) the distace between conductors should be as long as
possible to reduce inductance in case of ac transmission
3) highly conducting meterials based on the economy have to
be taken such as aluminium
4)power factor should be more .the more the power factor is
the less the current is .so losses are reduced
5)hvdc transmission is also another option

Answer / anil

By reducing current because 'cu' loss depends on current

Proviiding the Dedicated N earth and individual Body Earths ,Finally these all looped /Now my Question :- will it not harm in case of Transformer Fault current flows in Dediacted N Earthing to Looped Body Earthing.
