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
Ex:
440 V, 1.1kV, 6.6kV, 11kV, 33kV, 66kV, 110kV, 220kV, 440kV
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 ?

Transmission level voltage is the amount of electrical potential difference between two points in a power grid. It is typically measured in kilovolts (kV) and is used to transmit electricity over long distances from power plants to local distribution networks.
Transmission level voltage is important because it allows electricity to be transmitted efficiently over long distances. Higher voltages result in lower electrical losses, which means more electricity can reach its intended destination. It also reduces the need for additional infrastructure, such as transmission lines, which can be costly and have negative impacts on the environment.
The typical range for transmission level voltage is between 69 kV and 765 kV. However, some systems may use higher voltages, up to 1,200 kV, for long-distance transmission.
Transmission level voltage is used for long-distance transmission of electricity, while distribution level voltage is used for delivering electricity to homes and businesses. Distribution level voltage is typically lower, ranging from 4 kV to 33 kV, and is used for shorter distances.
Working with transmission level voltage can be dangerous and requires proper training and precautions. Workers must follow strict safety protocols, including using appropriate personal protective equipment and following lockout/tagout procedures. Additionally, transmission lines should be clearly marked and kept clear of any obstructions to prevent accidental contact.
