This is the calculation of maximum demand in a specific interval (usually the integration period = 15
minutes). Once the number is calculated, it is refreshed every minute with the values from the last 15
minutes. In other words, every minute (this time can be variable) we will have a maximum demand
number for the last 15 minutes. The result would be 60 values per hour.

The CVM-C11 calculates the maximum demand of the following:
Current of the L1, L2, L3 and three-phase.
Three-Phase Active Power.
Three-Phase Apparent Power.
Three-Phase Inductive Reactive Power.
Three-Phase Capacitive Reactive Power.
In the configuration menu, the type of integration is selected, “6.10. TYPE OF INTEGRATION OF THE
MAXIMUM DEMAND” and the integration period of the maximum demand “6.11.- MAXIMUM DEMAND
INTEGRATION PERIOD”.
