Abstract

This report presents the results of an extensive survey of electric utility practices for the protection of distribution lines at substations. Results of similar surveys were published in 1983 and in 1988. In this survey, the first eight sections were comparable to the earlier surveys. In addition, these sections were expanded to collect more data on the reasons behind a practice and on the methods used. A ninth section was added to address the impact of dispersed sources of generation (DSG) on distribution protection. The responses to this survey have been compared to the previous survey in an attempt to detect any trends in the protection of distribution circuits
