Demand / Peak Demand for P, S Type
1. Demand Measurement, Peak Demand Record
1) P and S type Demands are calculated with an average of the active power during the Demand cycle.
2) Demand cycle can be set by divisors of 60 minutes (1, 2, 3, 4, 5, 6, 10, 15, 20, 30, 60 minutes).
3) These are Block Demand and Rolling Demand for the Demand measuring method.
P and S type only provide Block Demand for Demand method.
4) Block Demand measures by synchronizing with the minutes of internal timer of the P and S type.
In short, under condition of Demand cycle is set as 15 minutes, if it is turned on at 11:05, Demand can be
measured on 11:15 by using the average power during 10mins. After that, Demand can be measured again by
using the average power during 15mins on 11:30.
5) The maximum Demand value measured from every cycle is set as Peak Demand and its occurred date and the
value are recorded at nonvolatile memory.
