The theoretical approach to calculate short-circuit (s.-c.) currents with symmetrical components in general and especially in the case of single-phase short-circuit was explained in detail in Chapter 2. Current and voltages in case of short-circuits with earth connection (e.g., single-phase short-circuits) depend on the positive and zero sequence impedances Z1 and Z0.
