Hi this is manikandan an electrical engineer from chennai........ i am very glad to join in this forum. Let this be my first query

In india -
In the electrical power transmission-
why the transmission level voltages are multiples of 11

Example:

6.6kv, 11 kv,33kv, 66kv, 110kv, 220kv . If you find answer post me.

Pl find any technical reason beyond that....... are its traditional like our 50Hz story

    voltages will always b in the multiple of 1.1.
    those voltages which are not in the multiple of 1.1 are approximate.
    the exact theoretical voltage will always be a multiple of 1.1
