Why we are use 11KV / 22KV / 33KV / 66KV / 110KV / 230KV /
440KV this type of ratio. why cant we use other voltage
ratio like 54KV / 99KV et.,

Answer Posted / vivek sharma
When an alternator generates voltage, its rms value is given
by 4.4*f*$*t, where $ is value of total flux per pole. So we
can see all the voltages are made inevitably multiple of
this value (1.1, which is the form factor of ac wave). also
it provides us the best economic construction of step up and
step down transformers.

In both 600/1000 V cable and 450/750 V cable, we can supply 415 V. However for distribution, all utilities are using only 600/100 V instead of 450/750 V. What is the reason?
