Demand Measurements

General Description

Demand registers include:

current demand
active, reactive, and apparent power demand

The window duration of current demand depends on the configuration of register 3352 Demand Time.

The window duration and the window type of power demand depend on the configuration of registers 3354 and 3355 Demand Time.

The demand measurements are refreshed every minute with the sliding window type.

The demand measurements are refreshed at the end of the window interval with the block window type.
