5 Commissioning
The following sections with their subsections contain information on:
The devices and facilities required for the commissioning inspection.
The required procedure for the commissioning inspection; For example, depend-
ing on the components to be tested: Protection, interlock conditions, communica-
tions, measured value recording and determining the direction.
5.1
Safety Information
The devices, adapters and procedures described are only examples. Experience and
safety in handling the various devices is a requirement.
5.2
Switching on the feeder
Caution
Before switching on the feeder check that the REF542plus is fully functional in
the corresponding bay. Pay particular attention to the protective functions and
the interlocking!
5.3
Test Equipment
The most important device for the commissioning of the REF542
plus
is an appropri-
ate relay test equipment. The test equipment should have a three phase current and
voltage system. Also the simulation of current and voltage sensors by the test equip-
ment shall also be possible. For example a test equipment manufactured by KOCOS
in Korbach/Germany can be used.
5.4
Testing the interlock conditions,
This test is intended to check the interlocking of the switchgear that the user wants
and is required. The two types of interlocking must be taken into account here:
Bay-level interlocking of specific switchgear and
Station-level interlocking of the bay versus other bays.
The interlock conditions for the bay under test can be found in the order documenta-
tion. The interlock conditions specified by the user can be found there.
All possible circumstances must be checked.
