Answer Posted / girish
B'coz Form Factor of AC Sine Wave is 1.1 so Transmission
Voltages will always be the integral multiples of 11
for eg. 220, 440, 660, 1100, 3300, 6600, 11000, 33000,
66000, 110000
Form Factor = RMS Value of Sine Wave / Average Value of Sine
Wave
RMS Value = 0.707
Average Value = 0.683
0.707 / 0.683 = 1.1

What are the internal and external faults?
y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
