Commissioning/Protection Test
Commissioning/protection test must be carried out by authorized and qualified
personnel. Before the device is put into operation, the related documentation
MUST 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 waveform recorder?
Are all signals/messages correctly generated?
Do all generally configured blocking functions work properly?
Do all temporarily configured (via DI) blocking functions work
properly?
To enable checks on all LEDs and relay functions, these have to be
provided with the relevant pickup (alarm) and tripping functions of the
respective protection functions/elements. This MUST 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 MUST be tested. The test can be very
complex and should therefore be performed by the same personnel
who set up the protection concept.
Check all general trip blockings. All general trip blockings MUST be tested.
Prior to the initial operation of the protection device, all tripping times and
values shown in the adjustment list MUST 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.
