FUNCTION:
The SR469 can measure the demand of the motor for several parameters (current, kW, kvar, kVA). The demand values of motors may
be of interest for energy management programs where processes may be altered or scheduled to reduce overall demand on a feeder.
Demand is calculated in the following manner. Every minute, an average magnitude is calculated for current, +kW, +kvar, and kVA
based on samples taken every 5 seconds. These values are stored in a FIFO (First In, First Out buffer).The size of the buffer is dictated
by the period that is selected for the setpoint. The average value of the buffer contents is calculated and stored as the new demand
