Answer / manish sharma

In the case of a sinusoidal wave ie., an analogue wave, the
form factor is approximately 1.11.

Form factor of an alternating current waveform (signal) is
the ratio of the RMS (Root Mean Square) value to the
Absolute Average Value (also referred to as the Practical
Average Value) of the waveform.

Therefore due to form factor our volatges are 11KV, 33KV,
66KV ...
