Why Generating Voltage Is 11Kv?

It is cheaper to generate at a relative lower voltage and then step it up for transmission. Hence, most power generating plants

generating plants
Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.

are designed to operate at 11KV. ... Therefore in order to compensate for this, the primary generation voltage would be; the required nominal voltage + transmission losses.

Why all voltage levels are the multiples of 11kV?

Answer: When an alternator generates voltage, we always use a multiple of 1.11 because for a pure sine wave the FORM FACTOR is the ratio of rms value of voltage or current with the avg. ... value is 2Imax/pie and which comes out to be 1.1; We can't have a combination of other then a multiple of 1.11*.

Why 11kV is used in distribution system?

The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. ... This power can then be safely distributed in order to power a town near the transformer.
