9424200994 Rev N 219DemandsDemand recording promotes the ability of an electric power provider to plan for future upgrades. Forexample, increasing load, over time, at a substation will be reflected in the demand values. This growingdemand can be addressed through additional capacity before the increasing load becomes an issue.The BE1-11g continuously calculates demand values for current, watts, vars, and VA. Demand values arerecorded with timestamps for peak demands and present demands. Programmable alarm points can beset to alarm if thresholds are exceeded for overload and unbalanced loading conditions. For informationon enabling alarms, refer to the Alarms chapter.CurrentDemand values are continuously calculated for phase currents (IA Circuit 1, IA Circuit 2, IB Circuit 1, IBCircuit 2, IC Circuit 1, IC Circuit 2), neutral current (3I0 Circuit 1, 3I0 Circuit 2), negative-sequence current(I2 Circuit 1, I2 Circuit 2), and ground current (IG Circuit 1, IG Circuit 2).Demand Current Reporting SettingsBESTCOMSPlus Navigation Path: Settings Explorer, Alarm Configuration, DemandsHMI Navigation Path: Settings Explorer, Alarm Configuration, DemandsSettings are made using BESTCOMSPlus®.
