in the directional overcurrent and earthfault protection,normally we are setting the angle 45 deg lead for phase fault overcurrent and -45 deg lead for earthfault fro forward direction.but both the fault are operating on the same angle region only.why?how the relay will response?

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?
