Answer Posted / vipul tayal

it is simply due to FORM FACTOR becoz form factor for a
pure sine wave is 1.11 and in all systems whether 1 phase
or 3 phase it will be a multiple of 1.11 and leads to
voltages like 11,6.6,10.5,11 kv) etc.

how i calculate the syncrones generator NGR resistance .if we have a 6mw generator line voltage of generator 11kv also line current 393.3 ampere.
