Why do you represent the voltages ranges in terms of 11kilo Volt in power system?

It used to be a convention to add 10% to allow for transmission

losses, so the voltages were always described as 11 kV, 33 kV, 66

kV and 132 kV. Later standards in the UK grid are 275 kV, which is

a multiple of 11, and 400 kV which is not.
