NettetLine to Line Fault (LL): Figure 11.7 shows a Line to Line Fault at F in a power system on phases b and c through a fault impedance Z f. The phases can always be relabelled, such that the fault is on phases b and c. Equations (11.11) and (11.16) suggest parallel connection of positive and negative sequence networks through a series impedance Z f ...
