why the capacitor bank unit is kvar
Answers were Sorted based on User's Feedback
Answer / atish mane
Unit of capacitor is always in Farad, but here the role of
capacitor bank is reactive power compensation & we know that
the unit of reactive power is KVAR so how much compensation
that capacitor bank is providing is nothing but the KVAR
rating of that capacitor bank.

Answer / mohan
bcoz the capacitor banks only supply reactive power(kvar)to
the system. normally capacitor banks are used to maintain
p.f. of the system. and one important thing is capacitor
banks must be ON according to the load(if it is APFC,no problem)

ratings of lightning arrester
What is polar plot?
as per IE stranded what is max voltage between neutral to earth. 100 kva transformer neutral solid earth. min and max values i need to ans for RTI question
back emf of motor at the time of starting ?
how i sync. the different size of generator.
Can we generate 3 phase power from single phase connections?? If yes, how?
why select the 3 phase power supply system in electrical system.
why phase & neutral is use in tv? why earthing not use ?
( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR CAPACITOR BANK Answer # 1 The capacitor current would be kvar x 1000 / (415 x sqrt3). This would be 70a approx. The MCCB selected should have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So you should choose at least 100 A mccb.) regarding to this answer,i would like to know why the current have to times 1.4 to get the right amphere for the mccb.hows the formula to get the 1.4??tq
Thermal withstand capability under full short circuit conditions, in terms of number of times of occurrence of short circuit and corresponding anticipated percentage reduction in transformer life.
