V unbal, which is calculated as maximum difference between two phase voltages.
The protection activates if the voltage unbalance gets over the threshold for time
longer than Bank V unb del.
NOTE:
The voltage 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.
This setpoint adjusts the delay for the generator voltage unbalance protection.
The threshold for the protection is adjusted by setpoint Bank V unbal.
NOTE:
The generator voltage 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.
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 Bank 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.
