Answer Posted / 7anoter4
If the system is three-phase: KVAR=sqrt(3)*Icap[A]
*Volt/1000 then:
Icap=1000*kVAR/Volt/sqrt(3)
If the ambient temperature will remain the same and if
permissible conductor temperature will be the same then
copper bus bar cross section required will be 70%[approx.]
from Aluminum bus bar.
