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).
V-Unbalance
Voltage difference setting for tripping.
Difference between the amplitudes of the two voltage input
channels which results in tripping. The setting applies to all
three phases in the three-phase mode.
Delay
time delay between pick-up and tripping.
t-Reset
Time required for the measurement to reset after the tripping
condition has disappeared (reset ratio: 0.90).
