Answer Posted / s.rajkumar
In general the voltages are represented in RMS values which
is obtained by multiplying average value with form
factor..........in general voltages are taken in terms of
average values as you have said (10,20......) but as we
multiply it with form factor which is 1.11 for sinusoidal
waveform the voltages become 11Kv,21Kv,33Kv,66Kv...........
