Electrical faults on transmission and distribution lines are detected and isolated bysystem protective devices. Once the fault has been cleared, outage times can be reduced if thelocation of the fault can be determined more quickly. This guide outlines the techniques andapplication considerations for determining the location of a fault on ac transmission and distributionlines. The document reviews traditional approaches and the primary measurement techniques usedin modern devices: one-terminal and two-terminal impedance-based methods and traveling wavemethods. Application considerations include: two- and three-terminal lines, series-compensatedlines, parallel lines, untransposed lines, underground cables, fault resistance effects, and otherpower system conditions, including those unique to distribution systems.

IEEE Guide for Determining Fault Location on AC Transmission and Distribution Lines
Electrical faults on transmission and distribution lines are detected and isolated by system protective devices. Once the fault has been cleared, outage times can be reduced if the location of the fault can be determined more quickly. The techniques and application considerations for determining the location of a fault on ac transmission and distribution lines are outlined in this guide. Traditional approaches and the primary measurement techniques used in modern devices are reviewed: one- and two-terminal impedance-based methods and traveling-wave methods. Application considerations include: two- and three-terminal lines, series-compensated lines, parallel lines, untransposed lines, underground cables, fault resistance effects, and other power system conditions, including those unique to distribution systems.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
