Section 2 Commissioning
2.1 Preconditions
It is assumed that the REB500 protection system is already installed and all input
and output signals that have been configured are also wired and the optical fiber
cables are run and tested.
It must also be assumed that the busbars or sections of them are in operation and
that circuit-breakers and isolators are in the process of being installed or
maintained.
The commissioning engineer requires the operating instructions and the station
diagrams prepared by the respective engineering department.
The protection system may only be commissioned by trained commissioning
personnel.
The greatest care must be taken when testing a busbar protection
system on busbars in operation, as the consequences of unexpected
operation in due process of the commissioning can be extremely
serious.
The REB500 protection system is equipped with an extensive,
continuous self-supervision and diagnosis feature. All functions are
constantly monitored by the system software. The overall system
has been extensively tested by ABB before releasing the product.
It is therefore not necessary to re-test the internal protection
algorithm by secondary injection.
This manual is therefore restricted to verifying the correct
connection to the primary process.

16. Set the system time
17. Record traceability data
18. Final test and inspection
Since the methods to perform the above mentioned procedure should be well
known to the commissioning engineer, a detailed explanation is omitted. The
following paragraphs focus on items specific to the REB500
2.2.2 Commissioning with a partial system
In order to operate, the REB500 protection system requires signals from the
isolators and circuit-breakers indicating their status. If one or several positions are
unknown, the protection system starts incompletely. The system is only fully
operational and standing by when all the position signals are available.
At the beginning of commissioning, these signals are frequently incorrectly wired
or the supply for the auxiliary contacts is unavailable. To enable commissioning of
the protection system to proceed in spite of this, the positions of the isolators and
circuit-breakers have to be simulated. This can be achieved either using jumpers at
the terminals or by simulating optocoupler positions in the test mode.
The checks described in this document assume a system in a stable
stand-by mode, i.e. no alarms with the exception of “Test generator
active” may be active.
2.2.3 Comparison with the layout of the primary system
In order to operate correctly, the REB500 process image needs to reflect the actual
setup of the primary equipment in the substation. It is therefore important to verify
the correct engineering at the beginning and make sure that not yet installed parts
are masked accordingly.
The easiest way to verify this is by checking the layout in HMI500 using the
“Single-line diagram” in the “View” menu.
Check that the locations of the CTs in the single-line diagram
conforms to the actual primary system. This check is essential if an
end fault protection is installed, as it influences the tripping logic
and most tests do not disclose an incorrect location.

Commissioning
Commissioning Manual 9
Distributed busbar protection REB500
2.2.4 Checking the analog inputs (CTs)
Using a test set, inject a secondary current into each of the CT inputs.
The CT connections can be checked in one of the following ways:
·Reading the injected currents on the local HMI
(Note: The readings are referred to the primary values.)
·Reading the injected currents via HMI500 by selecting “Analog input
measurements” in the “View” menu
·Reading the injected currents via HMI500 by selecting “Protection zone
measurements” in the “View” menu
·Reading the injected currents via HMI500 by selecting “Single-line
diagram”
·Increasing the currents until a protection function picks up.
2.2.5 Checking the analog inputs (VTs)
Using a test set, inject a secondary voltage into each of the voltage transformer
inputs.
The checks can be executed in different ways:
·Reading the injected currents on the local HMI
·Reading the injected currents via HMI500 by selecting “Analog input
measurements” in the “View” menu.
Primary values of phase-to-neutral voltages are displayed.
2.2.6 Checking the binary input signals (optocoupler inputs)
Check the proper function of every binary optocoupler input by exciting the signal
source.
The binary inputs can be checked in one of the following ways:
·Reading the status on the local HMI

Section 2 1MRK 505 351-UEN
Commissioning
10 Commissioning Manual
Distributed busbar protection REB500
·Reading the statuses via the HMI500 by selecting “Binary input/output
status” in the “View” menu
·Checking the events generated in the event list.
Besides showing the correct operation, the event list also provides a
mean to check the correct functional assignment of the input.
2.2.6.1 Wiring for auxiliary contacts
The standard wiring of the N/C auxiliary contacts on L1, L2 and L3 phases of
isolators and circuit-breakers is in series and the N/O contacts in parallel.
This is reversed in case of the special version “not OPEN = CLOSED”.

Inverting the logic means that local events are generated while a bay unit is starting
that signal a change of input status that did not take place. Correct operation is
nevertheless unimpaired.
2.2.6.2 Checking the isolator and circuit-breaker auxiliary contacts
Check the timing sequence of the isolator auxiliary contacts by inspecting the
construction of the isolator or assessing it from the respective data sheet.
Verify the operation of the “CLOSED” and “OPEN” contacts
1. According to the circuit diagram and
2. by physically opening and closing the isolator. A check can be done in one
of the following ways
·Menu item “View àSwitchgear objects”
·Menu item “View àBinary input/output status”
·Menu item “View àSingle-line diagram”.
2.2.6.3 Checking the manual “CLOSE” command
The local HMI is the best way of checking the circuit-breaker “CLOSE” command,
because the signal is generated only briefly and the local HMI is refreshed the
quickest. The corresponding menu item is “Measurements/Inputs”.
Alternatively the circuit-breaker “CLOSE” command can be temporarily
configured as an event and its operation observed in the HMI500 event list.
2.2.7 Checking the binary output signals
Test operations of circuit-breakers and isolators require the
permission of the user and all the prescribed safety precautions must
be observed. Avoid unnecessary switching operations.
All binary inputs are tested by setting them appropriately in the test mode. Select
“Test mode” from the “Testing” menu and clock on “Unblock all relays” in the test
mode dialog.
In the test mode, select “Binary input/output status” in the “View” menu to view
the outputs of a binary module. The status of an output can be changed by double-
clicking on the corresponding field, which then changes to yellow.

Check that the correct circuit-breaker tripping coil is tripped by the
correspondingly configured tripping output. Repeat the procedure for the separate
alarm contacts.
2.2.8 Checking protection stability
The stability check verifies that all CTs are connected with the correct polarity and
have the correct ratio. All feeder and bus-tie breaker CTs must be connected,
otherwise the correct operation of the protection cannot be guaranteed.
Wherever possible the stability should be checked before the busbar is energized,
because the risk of a busbar fault is especially high when it is being energized for
the first time (flashovers, grounding isolators still closed etc.).
2.2.8.1 Checking through-fault stability with de-energized busbars
Inject a current from a primary injection test set (25 % of the CT rated current is
recommended) into two feeders (a reference feeder and one other feeder). Any
feeder can be used as reference. Compare each of the other feeders and bus-tie
breaker with the reference feeder.
Figure 2 Through-fault stability by primary injection (two feeders)
If a bus-tie breaker is only equipped with one set of CTs, note that they are used by
two busbar sections.
