Assessment of power lines performance based on voltage sag indices

Power lines performance has traditionally been assessed in terms of their efficiency and reliability. The increase of the effect of voltage sags on sensitive loads may be located far away from the faulted line, claims for a new analysis of line performance. A new method to evaluate power lines perfo...

Zusammenfassung:	Power lines performance has traditionally been assessed in terms of their efficiency and reliability. The increase of the effect of voltage sags on sensitive loads may be located far away from the faulted line, claims for a new analysis of line performance. A new method to evaluate power lines performance is proposed and compared with the previous ones based on the power line reliability. The results show that the new method can change the ranking of line performance and therefore the utility focus for investment.
