“POWER” CHART
System power trend chart (kW and kvar)
The chart compares the 2 system power magnitudes (kW: active system power; kvar:
reactive system power).
These values refer to the nstrument of choice (real or virtual according to the system
configuration settings).
Should the reference instrument be virtual, the powers shown in the chart represent the
sum of the system powers (kW and kvar) measured by each individual real instrument.
Data may be displayed on a daily, monthly or yearly basis.
Note : in charts the sampling frequency (current values for each phase), depends on the
storage interval set on VMU-C, which must be equal to 5,10,15,30,60 minutes.
