What is Fault Detector Settings for SEL Applications about?

This document discusses the philosophy for setting distance element fault detectors. It explains that phase current for a three-phase fault is higher than for a phase-to-phase fault. The setting can be 50% of the phase current for a three-phase fault to detect a phase-to-phase fault. Alternatively, it can be set to the phase-to-phase current for a three-phase fault, which will also detect a phase-to-phase fault since the currents are the same. Safety margins are ensured in both cases.
