Short Circuit Capacity.

An important aspect of power systems is its short circuit capacity which is the product of system voltage and fault current.Since the system voltage is assumed to be 1 pu and fault current is the ratio of system voltage to impedance as seen from fault point,the short circuit capacity is inversely proportional to system impedance as seen from fault point. A high short circuit capacity indicates that the system is strong or stiff.A low short circuit capacity means that the system is weak.Switching...
