Commissioning
Commissioning/Protection Test
Putting into operation/Protection test must be carried out by authorized and
qualified personnel. Before the device is put into operation the related
documentation has to be read and understood.
With any test of the protection functions the following has to be checked:
•
Is activation/tripping saved in the event recorder?
•
Is tripping saved in the fault recorder?
•
Is tripping saved in the disturbance recorder?
•
Are all signals/messages correctly generated?
•
Do all general parameterized blocking functions work properly?
•
Do all temporary parameterized (via DI) blocking functions work
properly?
•
To enable checks on all LEDs and relay functions, these have to
be provided with the relevant alarm and tripping functions of the
respective protection functions/elements. This has to be tested in
practical operation.
Check of all temporary blockings (via digital inputs):
•
In order to avoid malfunctions, all blockings related to
tripping/non-tripping of protection function have to be tested. The
test can be very complex and should therefore be performed by
the same people who set up the protection concept.
Check of all general trip blockings:
•
All general trip blockings have to be tested.
Prior to the initial operation of the protection device all tripping times and
values shown in the adjustment list have to be confirmed by a secondary
test
Any description of functions, parameters, inputs or outputs that does not
match the device in hand, can be ignored.
