6.3.6 VOLTAGE
6.3.7 DEMAND
The 745 measures current demand on each phase of each monitored winding. These parameters can be mon-
itored to reduce supplier demand penalties or for statistical metering purposes. Demand is calculated based on
the measurement type in
S2 SYSTEM SETUP/DEMAND METERING
. For each quantity, the 745 displays the demand
over the most recent demand time interval, the maximum demand since the last date that the demand data
was reset, and the time and date stamp of this maximum value.
