In practical cases the three phase voltages are not equal and there will be presence of potential at the neutral point and neutral is earthed to provide the path for unbalanced current during normal operation. The earthed neutral also helps during any abnormality in the system due to fault,it allows heavy currents to flow into the ground before the system isolated by means of protection system.

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.
