Table 5 Fault locations and tie switching in IEEE 33 bus distribution network
Faulted line | FPI flag status | Fault impedance range (Ω) | Power loss after the fault (no tie switching) in kW | Tie closed | Power losses after the fault (with tie switching) in kW | Tie chosen on the basis of minimum power loss (kW) | % Loss reduction on comparing power loss after fault without tie switching & with tie switching | |||
