•
AVERAGE CURRENT THD RELAY:
Excessive phase current THD 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 an excessive average
current THD condition exists. Selecting auxiliary relay will cause the auxiliary relay to activate, but no mes-
sage will be displayed. This is intended for process control.
•
AVERAGE CURRENT THD LEVEL:
When the measured average current THD exceeds this setpoint
value, an average current THD condition occurs.
•
AVERAGE CURRENT THD DELAY:
If the average current THD exceeds the
AVERAGE CURRENT THD LEVEL
for the time delay programmed in this setpoint, an average current THD condition occurs.
•
AVERAGE VOLTAGE THD RELAY
: Average voltage THD 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 an average voltage THD condi-
tion exists. Selecting auxiliary relay will cause the auxiliary relay to activate, but no message will be dis-
played. This is intended for process control.
•
AVERAGE VOLTAGE THD LEVEL:
When the measured average voltage THD equals or exceeds this set-
point value, an AVERAGE VOLTAGE THD condition occurs.
•
AVERAGE VOLTAGE THD DELAY:
If the average voltage THD equals or exceeds the
AVERAGE VOLTAGE
THD LEVEL
setpoint value and remains this way for the time delay programmed in this setpoint, an AVER-
AGE VOLTAGE THD condition will occur.
