how to calculate busbar size?
ex:11000kva main what is the busbar size ?and how to select
the correct one
Answer Posted / firoz kachhi
firstly calculate load current.
then we have std formula that is
current densty =current/area.
use std. current density for copper or aliminium
put it down in above formula and calculte busbar size.....
if u r area 100mm sq.....then we can use 50mm*2mm or 25*4mm
or 10*10....as per suitable ....very simple na??
