It is just the standard being maintained by all the transmission utilities, with form factor 1.11, voltage not even multiple of 11 is being under use, like 132kV,400kV etc, if this old standard is changed then it should be changed all over, from generating to distribution level, which is not possible in practical, hence the same std being maintained.
