The HT/EHT/MV voltages are mentioned as the multipliers of form factor ie. (3.14/2 root 2) = 1.1

Answer / k.prakashchandra

I had given answer to this long back.In the question
voltages are not correctly mentioned as V and KV.The first
electrical appliance was 100 V DC bulb.When AC system was
introduced ,the same bulb was used for 110 V AC applying the
form factor to make it equivalent.Then 11/33/ etc KV
systems came into being just have simple voltage ratio for
transformers.However we have 400 KV instead of 440 KV.

i am using auto transformer for starting of induction motor to provide reduse voltages...but the principle of a tansformer according to definition"which transform energy to on circuit to another circuit with constant power and constant frequency". so if i am using reduse voltage then current obsely hige because power is same.but we use auto transfarmer for starting of induction motor to give low current.but here according to definition we are giving hige current.
