Statistics data (Demand value group)
The user can keep track of the variable power quantities using the demand feature; the
statistical information (such as maximum load, minimum load, and averaged load) are
collected in every defined period.
Groups Displayed quantities

9.4.1
The statistics feature can provides the information about maximum, minimum, and averaged
values. Figure 9.4-1 shows the example about the current information
Max/Min/Averaged information about the demand feature
9.4.2
The demand feature is used to calculate the active power (P), the reactive power (P), and the
complex power (S) that are weighted with the plus (+) or minus (–) sign; the calculation will be
