Thermal demand
Thermal demand calculates the demand based on a thermal response, which imitates the function of thermal demand meters. The demand calculation updates at the end of each interval. You can set the demand interval from 1 to 60 minutes (in
The following illustration shows the thermal demand calculation. In this example, the interval is set to 15 minutes.

Current demand
The power meter calculates current demand using one of the methods described in “Power demand calculation methods” on page 79. You can set the demand interval from 1 to 60 minutes in
Predicted demand
The power meter calculates predicted demand for the end of the present interval for kW, kVAR, kVA and Amps demand. This prediction takes into account the energy consumption so far within the present (partial) interval and the present rate of consumption.
Predicted demand is updated every second.
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.
