Explanation of parameters:
ParSet 4..1
Parameter for determining in which set of parameters a par-
ticular function is active (see Section 5.11.).
Trip
defines the tripping channel activated by the tripping output of
the function (tripping logic).
Delay
Time between the function picking up and tripping.
XA-Setting
defines the first intersection of the impedance circle with the
reactance axis (assuming a phase correction setting of 0°).
Setting restriction: |X
A
| < |X
B
|.
XB-Setting
defines the second intersection of the impedance circle with
the reactance axis
(assuming a phase correction setting of 0°).
