Demand Measurements

Demand registers include:

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

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

For the block window, the demand value is updated at the end of the window.
For the sliding window,
- If window duration is configured for less or equal to 15 minutes, the demand value is updated every 15 seconds.
- If window duration is configured for more than 15 minutes, the demand value is updated every 1 minute.

The reset minimum/maximum command (command code = 46728) can reset the content of the peak demand measurement registers.
