Answer Posted / zulfiquar wani
Generator and transformer are rated in KVA becoz at that
time we dont know the consumer power factor as we know that
the (KW= KVA X Cos Phi) as we know the power factor we have
ratings in KW and on the other hand motor has defined power
factor and the rating has been mentioned in KW for example
if we have transformer of rating 50KVA this rating of
transformer is its apparent power that is KVA if we
multiply the same withh the power factor 0.85 we will get
the real power that is KW
KW= KVA X Cos phi
KW = 50 X 0.85
KW= 42.5KW

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.
