7.8.2 Functionality
GUID-2E34AB7F-886E-499F-8984-09041A89238D v6
The ZMFPDIS function is a six zone full scheme protection with three fault loops for phase-to-
phase faults and three fault loops for phase-to-ground faults for each of the independent zones,
which makes the function suitable in applications with single-phase autoreclosing.
In each measurement zone, ZMFPDIS function is designed with the flexibility to operate in either
quadrilateral or mho characteristic mode for separate phase-to-earth or phase-to-phase loops.
