The values for power metering appear here. Three-phase total power quantities are displayed here. Watthours and var-
hours are also shown here. Watthours and varhours will not update if a digital input programmed as Test Input is shorted.
An induction generator, by convention generates Watts and consumes vars (+Watts and –vars). A synchro-
nous generator can also generate vars (+vars).
If the VT CONNECTION TYPE is programmed as "None", the THIS FEATURE NOT PROGRAMMED flash message will appear
when an attempt is made to enter this group of messages.
