Is reverse power relay of generator operate due to voltage
variation problem? please clearify.
Answer / ram
Yes,Direction of Power flow depends upon the potential
difference.if bus voltage is greater than the generator
voltage ,there will a reverser flow.

How Size of Busbar is determined for a particular load.
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.
