Why HT voltages are expressed in 11KV,22KV,33KV and so on? (ie
in times of 11)
Answer Posted / k.prakashchandra
T.A. Edison invented the electric bulb which was working on
100 V DC.To get the same light output with that bulb,110 V
AC was required.Hence the form factor is responsible. If you
divide by 1.1 ,you get the average value.
