Demand Measurement Setup
The long-term averages are calculated and output by the 7SD80.
Functional Description
Long-Term Averages
The long-term averages of the three phase currents Ι
x
, the positive sequence components Ι
1
for the three
phase currents, and the real power P, reactive power Q, and apparent power S are calculated within a set
period of time and indicated in primary values.
For the long-term averages mentioned above, the length of the time window for averaging and the frequency
with which it is updated can be set.
