In this chapter, an outline of different types of short-circuits in three-phase a.c. systems is provided such as three-phase short-circuit,double-phase short-circuit without earth/ground connection, double-phase short-circuit with earth/ground connection and line-to-earth (line-to-ground) short-circuit. The method for calculating short-circuit current in a.c. three-phase high-voltage system is also provided.
