11.2.6.9 Setpoint: Mains Avg>V MP
This setpoint defines the trip level for mains overvoltage protection based on
10-minutes moving average of mains phase voltage. This protection is
evaluated in each phase and is activated immediately when the moving
average value exceeds limit adjusted by this setpoint.
11.2.6.10 Setpoint: Mains >f
This setpoint adjusts the threshold level for the mains overfrequency
protection. The threshold is adjusted in % of the mains system frequency
which is given by Nominal Freq and its offset Nom frq offset.
The protection activates if the frequency in phase L3 gets over the threshold
for time longer than Mains f del.
NOTE:
The mains overfrequency protection is Mains protection type - for more
information on protection types please refer to alarm types section.
11.2.6.11 Setpoint: Mains <f
This setpoint adjusts the threshold level for the mains underfrequency
protection. The threshold is adjusted in % of the mains system frequency
which is given by Nominal Freq and its offset Nom frq offset.
The protection activates if the frequency in phase L3 drops below the
