Other Properties Of Measured Variable Representation; Load Profile; Overview - Siemens SENTRON PAC4200 Manual

Parameterization of the averaging time
The averaging time can be parameterized on the display or via the communication interface.
The following can be set: 3, 5, 10, 30, 60, 300, 600, 900 seconds.

Other properties of measured variable representation

Zero point suppression level
The zero point suppression level can be set via the interface in 1% steps in the range from
0% to 10% of the measuring range final value (default value 0.0%). Currents within this
range are indicated on the display with "0" (zero).
Current direction
The current direction can be changed on the device or via the interface individually for each
phase. It is not necessary to change the terminal connections of the current transformers in
the event of connection errors.

Load profile

3.4.1

Overview

The load profile records the time history of the electric power and thus documents the
distribution of power fluctuations and peaks.
SENTRON PAC4200 supports load profile recording according to the "fixed block" or "rolling
block" method. With both methods, the load profile is stored in the device and made
available at the communication interfaces.
SENTRON PAC4200 is capable of intelligently interpreting synchronization signals received
at irregular intervals. Any deviations from the set times are documented in the load profile.
Accessing the load profile data
Note
Data access via the software
Current and historical load profile data can only be accessed via the communication
interfaces. For more information, please see the related documentation.
