Table 1 Comparison of discrete impedance points of fault in the network (Case 1) without & with FPIs
Actual fault impedance (Ω) | Discrete impedance point of fault detected by the system without FPI | Discrete impedance point of fault detected by the system with FPI |
|---|---|---|
10 | 1 | 1 |
20 | 2 | 2 |
30 | 3, 5 | 5 (if sensed by F1) 3 (if sensed by F2) |
40 | 4, 6, 8, 10 | 4 (if sensed by F2) 6, 10 (if sensed by F1) 8 (if sensed by F3) |
50 | 7, 9, 11 | 7, 11 (if sensed by F1) 9 (if sensed by F3) |
