Figure 31:
Operating characteristics of the GFC (impedance measuring principle) and zone
measuring elements
presents principally a shaped operate characteristic for an impedance based GFC func-
tion. Different designations have the following meaning:
•
XFW: reactive reach in forward direction
•
XRV: reactive reach in reverse direction
•
RF: resistive reach within the unlimited area
•
RLoad: resistive reach restricted by the minimum load impedance
•
LA: expected load impedance angle
