eswar310@gmail.com
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?
