Functions; Recorded Measured Values And Storage; Measured Value Acquisition - Siemens Sentron 7KN POWERCENTER 1000 Manual

Functions

The SENTRON circuit protection devices with communication and metering function offer
different functions depending on the respectively recorded measured values and setting
options.
6.1

Recorded measured values and storage

6.1.1

Measured value acquisition

The following measured values are recorded for the individual device types and e.g. displayed
in the SENTRON powerconfig app in the device overviews. A more detailed description of all
measured values and parameters can be found in Chapter Information categories of the
SENTRON circuit protection devices (Page 66).
Measured value
Temperature (inc. average)
Current (incl. average and maximum
value)
Voltage
Line frequency
Apparent, reactive, active power and
power factor
Reactive, active energy
Switching state of the attached device
Operating hours
Operating hours with load current
Mechanical switching cycles
Counter for short-circuit trips
Counter for tripping operations general
The 7KN Powercenter 1000 data transceiver itself does not support any of the
aforementioned circuit-related measured values. It has a measured value of the operating
hours, which is mentioned under the messages below. Likewise, the system time is set via
the 7KN Powercenter 1000, which is necessary to be able to provide trends and messages
with the correct time stamp (see chapter Time synchronization (Page 59)).
Measured values are displayed in the software as invalid, if they are not received for a specific
period of time. Counters that have not yet counted to at least the value 1 are also displayed
as invalid.
