Overview and Specications

Utility Peak Demand

The PXM 2000 Series provides user-congured Fixed Window or Sliding Window Demand modes.

This feature enables you to set up a customized Demand prole. Fixed Window Demand mode

records the average demand for time intervals that you dene (usually 5, 15 or 30 minutes).

Sliding Window Demand mode functions like multiple, overlapping Fixed Window Demands. You

dene the subintervals at which an average of demand is calculated. An example of Sliding

Window Demand mode would be a 15-minute Demand block using 5-minute subintervals, thus

providing a new demand reading every 5 minutes, based on the last 15 minutes.

Utility Demand Features can be used to calculate Watt, VAR, VA and PF readings. Voltage provides

an Instantaneous Max and Min reading which displays the highest surge and lowest sag seen by the

meter. All other parameters offer Max and Min capability averaged over the demand period (meter)

or true Min and Max (Gateway Card)..
