**5.5 LLL faults**

LLL faults have been applied at F1 to F7 locations as internal and external faults. Considered F5 fault as LLL fault and used at 15 s of simulation time for 0.3 s duration which is the internal fault for W2. In this case-5, the positive sequence voltages less than set value and as per algorithm the relay issue tripping after 0.001 s. It is important to note that in this case, relay R1 at W1 and R3 at W3 is also instantaneous as the fault is on the point of Common Coupling (POC).
