If you mean why that particular voltage was chosen, as opposed to, say, 256 V, then perhaps someone else could answer the question? If, however, you mean "How is a single-phase 240 V supply obtained?", then the answer is as follows:
A single-phase nominal voltage of 240 V is obtained by connecting a load between a line conductor and the neutral conductor of a three-phase system having nominal 415 V line-to-line voltage.
This is the standard low-voltage supply used in the UK although, these days, we pretend that it is 230/400 V in order to meet the EU's harmonisation requirements.

What size cable for single phase 240volt carrying 65amps over 150 meters?
A 2/0 AWG copper conductor will limit the voltage drop to 3% or less when supplying 65 amps for 150 metres on a 240 volt system.
Is the type of wiring in most homes single-phase or three-phase?
Single phase.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
Is Europe ac power single phase?
In Europe they have both single phase and three phase.
How do you convert a 3-phase system to a single phase?
By having a transformer with 3 phase input and single phase out put
How single phase preventer working?
working of single phase preventor
What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
How do you derive three phase single way?
3 phase /sqrt(3) * 30 degree phase shift = single phase.
How do you connected 3 phase motor to single phase power?
Use VFD to make 3 phase from single phase source.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
