Description
This alarm evaluates the unbalance of the phase voltages, i.e. the difference
between highest and lowest phase voltage at any given time. The following
setpoints are related to it:
Voltage Unbalance BOC (page 200)
adjusts the maximum allowed difference
between the highest and lowest phase voltage at any given time.
Voltage Unbalance BOC Delay (page 200)
adjusts the alarm delay.

Description
The overcurrent alarm is based on IDMT principle. The reaction time of an IDMT
alarm is not fixed, but depends on how much is the protected value (generator
current in this case) above the limit (
). The higher is the
overcurrent, the shorter the reaction time will be. All generator phases are
evaluated.
The behaviour of the overcurrent alarm is adjusted by the following setpoints:
IDMT Overcurrent Delay (page 196)
defines the reaction time of the
protection when the current is twice the amount of nominal value.
set the nominal current level, where the alarm
starts to be evaluated. The reaction time is infinite at this point.

Description
The alarm is issued when the gen-set power is over the limit for time period longer
than the delay. The behavior of the overload alarm is adjusted by the following
setpoints:
adjusts the overload limit.
