Lateral Fuses and Reliability

Improving protection and control for distribution systems

BY STEVE GREEY, S&C Electric

In 2008, Toronto Hydro completed a study of its worst performing feeders (distribution system feeder lines). This study identified the utility’s distribution feeders with the poorest reliability. The study raised an interesting question: “Why do lateral fuses which, since the 1930s, have been the most effective way of increasing reliability, provide adequate reliability on some of the 27.6-kilovolt distribution feeders and not others?”
