This setpoint adjusts the threshold level for the generator current unbalance
protection. The threshold is adjusted in % of the generator nominal current. The
protection is Breaker open and cool down type and is created in the default
archive as universal analog protection at the value Gen I unbal, which is
calculated as maximum difference between two phase currents.
The protection activates if the current unbalance gets over the threshold for time
longer than Gen I unb del.
NOTE:
The current unbalance protection is created in the default archive using the
mechanism of universal analog protections. That means this setpoint is one of
general-purpose setpoints, which may be used for different purpose if the
protection is deleted from the configuration.
Setpoint: Gen I unb del
This setpoint adjusts the delay for the generator current unbalance protection. The
threshold for the protection is adjusted by setpoint Gen I unbal.
NOTE:
The generator current unbalance protection is created in the default archive using
the mechanism of universal analog protections. That means this setpoint is one
of general-purpose setpoints, which may be used for different purpose if the
protection is deleted from the configuration.
Group: Mains protect
Setpoint: Mains >V MP
This setpoint adjusts the threshold level for the mains overvoltage protection. The
threshold is adjusted in % of the nominal mains voltage, which is either
MainsNomV or MainsNomVph-ph, depending on the position of the setpoint
FixVoltProtSel.
The protection activates if the voltage in at least one phase gets over the
threshold for time longer than Mains V del.
NOTE:
The asociated protection to this setpoint is Mains protect type. This type of
protection is recorded into the history file, however it is not indicated in the Alarm
list. When a protection of Mains protect type occurs the controller opens either
MCB (in applications where the MCB is controlled) or GCB (in applications where
