Not actually by 11 but by 2 or by square-root of three. The reason is for simplier construction of transformers. The typical voltage rating of the transformer dictates the voltage level of the transmission and distribution system. Square-root of three on the hand is involved because of different types of transformer connection or vector group.

Its due to the form factor (for sinusoidal waves it is 1.1)
