(Hysteresis: 0.05 Hz)
(Reset Delay: 80 ms)
The percentage values that are to
be monitored for each threshold
limit are defined here.
If this value is reached or
exceeded for at least the delay
time without interruption, the
action specified by the alarm class
is initiated.
Notes
This value refers to the System
rated frequency (parameter

1911: [0.30 s]
If the monitored generator
frequency value exceeds the
threshold value for the delay time
configured here, an alarm will be
issued.
Notes
If the monitored generator
frequency falls below the
threshold (minus the hysteresis)
before the delay expires the time
will be reset.
