Manual SENTRON Power Monitoring Device SENTRON PAC4200

Description
3.4 Load profile
Configuring load profile recording
You can adapt load profile recording using the configuration software or on the display of the
device. The following parameters influence the recording:
● Length of the demand period or subperiod
● Number of subperiods per demand period. This number defines the method for recording
the load profile ("fixed block" or "rolling block")
● Type of synchronization
You can also set the following parameter with the configuration software:
● Type of reactive power VARtot, VAR1, or VARn
You can find more information about parameterization on the device display in the chapter
"Parameterizing", "Power demand".
Changing the configuration during operation: If the period length or the number of subperiods
is changed, this directly influences the load profile recording. The device stops the current
recording and clears all data in the load profile memory. Changing the configuration has no
effect on the device counter. The device is not reset.
Load profile recording methods
SENTRON PAC4200 supports the following load profile recording methods:
● Fixed block
● Rolling block
The default setting is the fixed block method with a demand period length of 15 minutes.
