Answer Posted / denzel101
Calculate the maximum current you want to measure from your
system. for example calculate the full load current of a
supply transformer. if the full load current is 200 Amps
and your meters have 1amp rating, choose the ratio of 200:1
CT.

what is through fault?
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?
