Variation of Per-Unit VL-N With Increase in Faulty Elements/units

This document contains a graph showing the variation of per-unit line-to-neutral voltage (VL-N) for a fuseless self-contained breaker (SCB) as the number of faulty elements or units increases from 0 to 5. The VL-N decreases gradually from its nominal value of 1 per unit as more faulty elements are introduced, reaching a minimum value of around 0.94 per unit at 5 faulty elements.
