Commissioning Checking parameter
and protection settings
7/24
Determination of parameter and protection settings
All of the Sepam parameter and protection settings are determined beforehand by
the design department in charge of the application, and should be approved by the
customer.
It is presumed that the study has been carried out with all the attention
necessary, or even consolidated by a network coordination study.
All of the Sepam parameter and protection settings should be available at the time of
commissioning:
b in hard copy format (with the SFT2841 software, the parameter and protection
setting file for a Sepam can be printed directly or exported to a text file for editing)
b and, when applicable, in the format of a file to be downloaded into Sepam using
the SFT2841 software.
Checking parameters and protection settings
Check to be made when the Sepam parameter and protection settings have not been
entered or downloaded during commissioning testing, to confirm the conformity of
the parameter and protection settings entered with the values determined during the
study.
The aim of this check is not to confirm the relevance of the parameter and protection
settings.
1. Go through all the parameter and protection setting screens in the SFT2841
software, in the order proposed in guided mode.
2. For each screen, compare the values entered in the Sepam with the values
recorded in the parameter and protection setting file.
3. Correct any parameter and protection settings that have not been entered
correctly, proceeding as indicated in the "Use of the (SFT2841) software" section of
this manual.
Conclusion
Once the checking has been done and proven to be conclusive, as of that phase, the
parameter and protection settings should not be changed any further and are
considered to be final.
In order to be conclusive, the tests which follow must be performed with these
parameter and protection settings; no temporary modification of any of the values
entered, with the aim of facilitating a test, is permissible.
