• POWER ALARMS LEVEL BASE UNIT(S): This setpoint is used to select the base unit
multiplier for all power alarms. When set to kW/kvar, all power alarm levels can be set
in terms of kW and kvar with a step value of 1 kW/kvar. When set to MW/Mvar, all
power alarm levels can be set in terms of MW and Mvar with a step value of 0.01 MW/
Mvar.
• POSITIVE/NEGATIVE REAL POWER RELAY: The positive and negative real power level
detection can be disabled, used as an alarm, or used as a process control. The “Off”
setting disables this feature. Selecting “Alarm” activates the alarm relay and displays
an alarm message whenever a positive/negative real power level exceeds the
selected level. Selecting an auxiliary relay activates the auxiliary relay for a set level of
