Objectives: Why Fault analysis? ⚫ Goal of fault analysis is to determine the magnitudes of the currents present during the fault: – To determine the maximum current that devices can withstand during fault. –To determine the maximum current the protective devices CB (circuit breakers, relays …) need to interrupt to correctly size the CBs. Relays

Text from page-4

Introduction • The electrical power system normally operates in a balanced three-phase sinusoidal steady-state mode. • However, there are certain situations that can cause unbalanced (abnormal) operations. • Therefore protective devices should isolate faults at a given location safely, with minimal damage.
