1010603 Symmetrical Faults
Introduction Up to now, we have studied the power system under normal operating conditions. Any failure in a power system which causes short circuit of a section is called a fault. This short circuit creates a low-impedance path through which fault currents greater than normal condition can flow. As these fault current magnitudes can be several times larger than normal, they may cause damage to the power system equipment. These damages could be categorized as electrical and mechanical. From the electrical view point, excessive current flow may cause thermal damage to solid insulation or metallurgical damage to conduct…
