PQM POWER QUALITY METER – INSTRUCTION MANUAL 4–47
• OVERFREQUENCY DELAY: If the overfrequency equals or exceeds the
OVERFREQUENCY LEVEL setpoint value for the time delay programmed in this
setpoint, an overfrequency condition will occur.
4.5.4 Power Alarms
FIGURE 4–27: Setpoints Page 4 – Alarms/Control / Power
• POWER ALARMS LEVEL BASE UNITS: 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 REAL POWER RELAY: Positive real power level detection can either be
disabled, used as an alarm or as a process control. Set this setpoint to off if the feature
is not required. Selecting alarm relay will cause the alarm relay to activate and display
an alarm message whenever a positive real power level exceeds the selected level.

** These setpoint ranges are dependent upon the POWER ALARMS LEVEL BASE UNITS setpoint.
If POWER ALARMS LEVEL BASE UNITS = kW/kVAR, then the ranges are in kW/kvar.
If POWER ALARM LEVEL BASE UNITS = MW/Mvar, then the ranges are in MW/Mvar
