In underground cables,we have a grading method called
'capacitance grading'.Why is it called 'capacitance grading'
although we do not use any capacitor in it?

Capacitance grading means not the use of
capacitor.Particularly in signal cable capacitance grading
is important. In any cable leakage is depends on the
capacitance between core to core and core to earth.If the
capacitance is high leakage also high.

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?
