Power Demand

Power demand is a measure of average power consumption over a fixed time interval.
NOTE: If not specified, references to “demand” are assumed to mean “power demand.”
The meter measures instantaneous consumption and can calculate demand using various methods.

Current demand

The meter calculates current demand using the block interval, synchronized or thermal demand methods.
You can set the demand interval from 1 to 60 minutes in 1 minute increments (for example, 15 minutes).

Predicted demand

The meter calculates predicted demand for the end of the present interval for kW, kVAR, and kVA demand, taking into account the energy consumption so far within the present (partial) interval and the present rate of consumption. Predicated demand is updated according to the update rate of your meter. The following illustration shows how a change in load can affect predicted demand for the interval. In this example, the interval is set to 15 minutes.
