The current that is passing through winding creates magnetic
flux, some part of the flux links with the core of the
transformer, due to this core experience the magnetic
simulation of electrons and then the electrons will
continuously change the direction due to magnetic field and
some time they align in one particular direction and they
will not change the direction irrespective of continuous
magnetic field, hence we will use the term saturation of
core at that point of time.

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?
