Answer Posted / sudhakar

we need around 800 to 1000 volts to start ionisation of the
medium which is present between the 2 electrodes of the
tube.once the ionisation starts the conductivity of medium
increases and 110 volts is sufficient to sustain the
emission of electrons from electrodes.
so to produce such a high voltage we are using choke.
once it starts to reduce the 230V to 110 volts we are using
the same choke.

Why 11kv to be generated in generation station
