Description This setpoint adjusts excitation loss protection level. Corresponding level in kVA is
calculated from
setpoint (e.g. this setpoint is adjusted to 50% and nominal power of gen-set is 200
kW, therefore excitation loss protection level is set to -100 kVAr)
Delay for this protection is given by the setpoint
This protection is breaker off and cooldown type. For more information on

Description This setpoint adjusts the threshold level for the generator voltage unbalance
protection. The threshold is adjusted in % of the nominal generator voltage, which
is either
FixVoltProtSel. The protection is Breaker open and cool down type and is created
in the default archive as universal analog protection at the value Gen 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
N
OTE
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.
