Current Demand

Power Demand

339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
The relay measures Current Demand on each phase. 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
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 with the
