AC voltages are sinusoidal in propagation. the electrical machines are designed for root mean square(RMS) values of voltage which is nothing but equivalent D.C voltage.whereas insulation, transmission etc are calculated for average(AVG) values which is 1.1 times RMS value.1.1 is form factor for sinusoidal waves. (form factor = RMS value/ AVG value). so a generator may be producing 400 kV RMS but in common mans' term it will be 440kV.
