5.1
Operation in normal case
The basic operation procedures in normal IED use situation are:
•
Monitoring of measured values
•
Checking the function setting parameters
•
Checking the test data
All basic operations can be performed via the LHMI, WHMI or with PCM600.
For more information, see PCM600 documentation.
5.1.1
Function settings
To check the correct operation of the IED, check the function settings via the
LHMI, WHMI or PCM600.
5.1.2
Test data
The IED's functions can be tested to ensure correct operation. After a specific test,
you can analyze the results.
5.2
Disturbance case operation
The IED is designed to identify and indicate several types of disturbances. The main
purpose of a protective IED is to identify power system disturbances and operate
according to the disturbance to avoid damage for power system equipment and people.
In other words, to disconnect the disturbance from the healthy network.
Many disturbance origins are permanent and cannot be automatically cleared. The
IED then collects disturbance data for later analysis.
Only authorized and skilled personnel should analyze possible errors
and decide on further action. Otherwise, stored important disturbance
data can be permanently lost
