Answer Posted / iamdon
star coonection reduces the voltage appering across each
phase by root 3 times.It means we need to design the
insulation for lower voltage which is economical.Also due
to reduced voltage reduced currrent will flow through
winding so less loss so less heating of winding so less
cooling requirement for keep the temperature rise within
limit.
All these beauty will lost in delta connection.So delta is
not preferred..

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?
