What is the Frequency while we step up the voltage from
220V to 11KV? Is it possible? Explain it?

Answer Posted / fransis

Generally Frequency is maintained by generation station for
a common distribution system.It is not possible to change
frequency while step up or step down the voltage on any
transformer.
This is also possible to change the frequency by term of
electronic controll device like in soft starter. In the soft
starter frequency is controlled with voltage to control the
speed of motor.
