CURRENT DEMAND CHAPTER 11: METERING
Current Demand
NOTE:
The number of Current Demand supported is Order Code dependent.
The relay measures Current Demand on each phase, and three phase Demand for real,
reactive, and apparent power. These parameters can be monitored to reduce supplier
Demand penalties or for statistical metering purposes. Demand calculations are based on
the measurement type selected under
Monitoring > Functions > Demand. For each
quantity, the relay displays the Demand over the most recent Demand time interval, the
maximum Demand since the last maximum Demand reset, and the time and date stamp
of this maximum Demand value. Maximum Demand quantities can be reset to zero at
Records > Clear Records > Max Current Demand.
