Answer / sindhu

at high voltage I^2r losses r less

Answer / arunkumar

since when we have high voltage ,wat about current ...ya we
have low current..we can save conductor material for
transporting power with high voltage low conductor..

Answer / ram

power losses inversly prop to square of voltage

Answer / prashant

This is directly related to ohms law V=IR. now from this
its quite evident that V and I are inversely related to
each other. So if V is higher then consequently the I will
be lower and hence the size of the conductor neede to
transmit the power will be small.Considerable cost saving

Answer / arunkumar

why i2*r loss is less...becoz we have low current at high
voltage

Answer / shahin

the main reson for high voltage transmission for reducing
line loss and improving the efficiency. Another reason for
high voltage transmission is Long distance transmission.

Answer / g.t.manikandan

For transmitt the power at higher voltage are
1.Reducing line loss(I^2 R)
2.Improve efficiency
3.Save Material Cost

Answer / achin bansal

AT HIGH VOLTAGE LINE CURRENT IS LOW THEREFORE LINE LOSSES
I2R WILL BE LESS AND OVERALL LINE EFFICIENCY WILL BE HIGH....

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
