5.4.3 Functionality
The fault locator function SCEFRFLO provides impedance-based fault location. It
is designed for radially operated distribution systems. It is applicable for locating
short circuits in all kinds of distribution networks. Earth faults can be located in
effectively earthed and in low-resistance or low-reactance earthed networks. Under
certain limitations, SCEFRFLO can also be applied for an earth-fault location in
unearthed distribution networks.
