difference between silent and non silent pole rotor?
Answer Posted / vikas mudhai
silent pole rotor-
1)used in low speed alternators(hydro-generator)
2)more no. of poles(4 to 64)
3)large diameter & small axial length
non-silent pole rotor-
1)used in high speed alternators(turbo-generator)
2)less no. of poles
3)small diameter & long axial length

following are the questions asked in interviews: 1) Considering the short circuit fault, which switchgear is preferable, SFU OR MCCB? Which operates faster? whicg one is popular in Indian Market and why? 2)Define SCPD. What is type2 coodination? 3)Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4)If the HP rating is known then can you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart?
