5 Testing
5.1 General
The operating values of the current and voltage measuring elements and
corresponding functions within the REx 5xx protection, control and mon-
itoring terminals must be checked during the commissioning and during
regular maintenance tests. ABB Network Partner recommends, although it
does not absolutely request, the use of testing equipment of type RTS 21
(FREJA) for purposes of secondary injection testing.
The test equipment used should be capable of providing an independent
three-phase supply of voltages and currents to the tested terminal. It must
be possible to separately change the values of voltages, currents, and
phase angles among the measuring quantities, independent of each other,
for each phase. The test voltages and currents should have a common
source, with a very small content of higher harmonics. If the test equip-
ment cannot indicate the phase angles between the measured quantities, a
separate phase angle meter is needed.
Before testing, it is necessary to connect the testing equipment according
to the valid terminal diagram of the particular REx 5xx terminal. Pay spe-
cial attention to the correct connection of the input and output current ter-
minals, and to the connection of the residual current. Follow these steps to
test the loss-of-power system voltage function :
1.1
Activate the operation of the function under the submenu by setting
the parameter Operation = On:

1.2
Check if the input and output logical signals as shown in Fig. 1 are
configured to the corresponding binary inputs and outputs of the
tested terminal. If not, configure them for testing purposes. The
configuration of the LOV--VTSU and LOV--BC functional inputs,
respectively occurs under the submenu:
Configuration
FunctionInputs
LossOfVoltage
The LOV--VTSU signal should be configured to the FUSE-VTSU
output signal under the fuse failure supervision function. The LOV-
-BC signal should be configured to one of the available binary
inputs of the tested terminal.
