India's transmission voltages are standardized in multiples of 11, including values such as 440 V, 1.1 kV, 6.6 kV, 11 kV, 33 kV, 66 kV, 110 kV, 220 kV, and 440 kV. This pattern is not directly related to resistance values, as resistance varies with transmission line lengths. The choice of these voltage levels is influenced by historical practices rather than global standards, as confirmed by discussions referencing sources like Wikipedia on electric power transmission history.
PREREQUISITESElectrical engineers, power system designers, and students studying electrical transmission systems will benefit from this discussion.
Truthlover said:it's look like that they used the same matricial patern of the resistances
Truthlover said:what i mean is that it's seem like they used the same valors of those used on the resistance. Like 110 ohms or 44kohms
berkeman said:No, that wouldn't be the reason. To cutiermn, I don't know why they use those values. Certainly 110, 220, 440Vrms are pretty standard values used in other parts of the world. I don't know the rationale for the higher voltage choices, though.

That's a good question. I did some searching on how transmission line voltages are chosen. The only thing I could find was a little history on http://en.wikipedia.org/wiki/Electric_power_transmission#History". I guess there are no world standards and depends on the history of the region.cutiermn said:In India why the transmission level voltages are in multiiples of 11 ?
Ex:
440 V, 1.1kV, 6.6kV, 11kV, 33kV, 66kV, 110kV, 220kV, 440kV
