If you multiply R (resistance in ohms) by C (capacitance in
microF) you'll get a value equal to the time constant of
the circuit in seconds. Remember that Xc = 1/(2*PI*F*C) and
that F = 1/T, then substituting and leaving out all
constants and applying a dimensional analysis you'll get
R*C = Time in sec. for that particular cct. (theoretical
value).

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.
