Table 1 Power interruptions caused by a fault at B4 based on Fig. 1a
| Â | Load nodes | Interruption duration per year due to the faults at B4 |
|---|---|---|
Load nodes lying upstream to the faulty branch, B4 | 2, 3, 4, 7 | \(\lambda_{B4} .\delta t_{B4}\) |
Load nodes lying downstream to the faulty branch, B4 | 5, 6 | \(\lambda_{B4} .\delta p_{B4}\) |
