Demands

Demand recording promotes the ability of an electric power provider to plan for future upgrades. For
example, increasing load, over time, at a substation will be reflected in the demand values. This growing
demand 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 are
recorded with timestamps for peak demands and present demands. Programmable alarm points can be
set to alarm if thresholds are exceeded for overload and unbalanced loading conditions. For information
on enabling alarms, refer to the

Current

Demand values are continuously calculated for phase currents (IA Circuit 1, IA Circuit 2, IB Circuit 1, IB
Circuit 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).
