I agree with you ram to some extent.
i have visited some power generating stations where the bus
bars are made of thick hollow spherical copper or aluminum
conductors.
Reason being that AC always has the tendency to flow on the
outer surface of the conductor which we call the skin effect.
I have seen rectangular strips too but not on the generating
stations but on the panels.
donno the exact reason behind

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
