The 469 measures motor demand for several parameters (current, kW, kvar, and kVA).
These values 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 as follows. 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 buffer size is dictated by the settings demand
