Answer / jwalith

hi,
the voltages here all are multiples of 11 because of the form factor(1.11).that is the reason we find 11,33,66...132,440,765..etc

Answer / jatin patel

Alternator output voltages are typically restricted to around
25 kV to limit their physical size and the centrifugal forces
to which they are subjected. In the UK, this voltage is then
typically raised to 400 kV for transmission.

The voltages to which you are referring to are typical of the
voltages used in the UK's high-voltage distribution system.
'Grid' substations typically transform transmission voltages
of 132 kV down to 33 kV (or, less commonly, 66 kV), and
'primary' substations then transform distribution voltages of
33 kV down to 11 kV.
