In case of stator earth-fault protection of generator, the value of resistance necessary in the neutral circuit to prevent an overvoltage due to resonance is ______.

Question

TuteeHUB · Accepted Answer

${R_n} = \frac{1}{{6\pi fc}}{\rm{\Omega }}$

TuteeHUB · Answer

${R_n} = \frac{{{{10}^3}}}{{\pi fC}}{\rm{\Omega }}$

TuteeHUB · Answer

${R_n} = \frac{{{{10}^6}}}{{6\pi fC}}{\rm{\Omega }}$

TuteeHUB · Answer

${R_n} = \frac{{{{10}^6}}}{{6f}}{\rm{\Omega }}$
