Why 11kv and 33kv

In ancient times when we needed to use 10 kV at destination, simply multiplied the form factor to it Say 1. Post New Answer. What can be maximum current handling capacity of a 2. Why do we generate 3 Phase AC Supply?

It is possible to generate 4 Phase and 5 Phase explain it? ICT tested and found in order. Many people question why the voltage is as high as 33kV in the first place. The reason is that the higher the transmission voltage, the lower the transmission losses will be. Therefore, the longer the distances that the power needs to be transferred, a higher voltage is used to reduce the transmission losses.

Overall, High Level of Voltages transmission is more prefer over high current transmission while the rating of power in kVA is same. Due to this problem, We may not transmit very high level of voltage i. But in recent days, We have distributed generation system.

This way, we may generate 1kV, 2kV, 3kVand so on instead of 11kV in form of wind power, solar power etc. So this rule is also eliminated.

Same answer mentioned for question number 5. If we transmit high current as compare to high voltage while the rating of power in kVA is same, We will have to need more size of conductors to handle the current.

The more current, The more Line Losses I 2 R , more heat, low power factor, skin effect, more distance between lines mean more materials for towers and poles and we would have need large number of rating machines like power and distribution transformer to handle this case.

This is why we only transmit high level of voltage instead of high level of current while the power rating in kVA is same. Your email address will not be published.

Not 10kV?
