A three-phase, 4-pole, self excited induction generator is feeding power to a load at a frequency f 1 . If the load is partially removed, the frequency becomes f 2 . If the speed of the generator is maintained at 1500 rpm in both the cases, then

Correct Answer is : f1, f2 < 50 Hz and f2 > f1

f 1 , f 2 < 50 Hz and f 2 > f 1

A three-phase, 4-pole, self excited induction generator is feeding power to a load at a frequency f₁. If the load is partially removed, the frequency becomes f₂. If the speed of the generator is maintained at 1500 rpm in both the cases, then

f₁, f₂ > 50 and f₁ > f₂
f₁ < 50 Hz and f₂ > 50 Hz
f₁, f₂ < 50 Hz and f₂ > f₁
f₁> 50 Hz and f₂ < 50 Hz
