In This case no other detail is given except the power
rating .
Therefore pf=( KW/KVA)
In order to get incentive and good power factor it is
required to maintain power factor above 0.95
So we take pf=0.95 and kw=(65*0.746)=48.49
Therefore KVA= 48.49/0.95 = 51.04
We know that KVAr= Squareroot( (KVA)^2-(KW)^2)
Therefore KVAr = sqrt(51.04^2-48.49^2)
=15.90 approx..
Capacitor required = 16KVAr.

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.
