Metered Parameters
The power monitor calculates and returns the following demand values:
•
Real power demand, kW
•
Reactive power demand, kVAR
•
Apparent power demand, kVA
•
Demand power factor, percent lagging (-) or leading (+)
•
Projected kW, kVAR, and kVA demand
•
Demand interval elapsed time, minutes
Projected demand calculates a linear projection of demand at the end of a demand interval.
Demand power factor is calculated using the following formula.
kW Demand / kVA Demand
Setup
Demand metering requires basic analog input setup as well as demand calculation setup. Basic
demand set-up parameters are found in the Advanced Setup menu. Network demand
synchronization is available on units connected to an Ethernet network. Network-demand
synchronization set-up parameters are found in the Ethernet communication set-up menu.
