The calculation of short circuit currents is a central task for Power System engineers, they are essential parameters for the design of electrical equipment and installations, the operation of power systems and the analysis of outages and faults.In the case when the busbar-coupler K in the power station is closed, the three- phase short-circuit current at the busbar is Ik3 = 37.6 kA; the short-circuit ... can be transferred to the power system without overloading any of the cable even under outage conditions. ...
