Testing IED operation

Preparing the IED to verify settings

If a test switch is included, start preparation by making the necessary connections
to the test switch. This means connecting the test equipment according to a specific
and designated IED terminal diagram.
Put the IED into the test mode to facilitate the test of individual functions and
prevent unwanted operation caused by other functions. The test switch should then
be connected to the IED.
Verify that analog input signals from the analog input module are measured and
recorded correctly by injecting currents and voltages required by the specific IED.
To make testing even more effective, use PCM600. PCM600 includes the Signal
monitoring tool, which is useful in reading the individual currents and voltages,
their amplitudes and phase angles. In addition, PCM600 contains the Disturbance
handling tool. The content of reports generated by the Disturbance handling tool
can be configured which makes the work more efficient. For example, the tool may
be configured to only show time tagged events and to exclude analog information
and so on.
Check the disturbance report settings to ensure that the indications are correct.
For test functions and test and signal parameter names, see the technical manual.
The correct initiation of the disturbance recorder is made on start and/or release or
trip from a function. Also check that the wanted recordings of analogue (real and
calculated) and binary signals are achieved.
The IEDs in the 650 series can have between 1 to 4 individual parameter setting
groups prepared with full sets of different parameters for all functions. The purpose
of these groups is to be able to handle different power system load conditions to
optimize the parameters settings of the different functions for these different power
systems conditions (for example summer/winter and day/night).
Parameters can be entered into different setting groups. Make sure
to test functions for the same parameter setting group. If needed,
repeat the tests for all different setting groups used. The difference
between testing the first parameter setting group and the remaining
is that there is no need for testing the connections.
During testing, observe that the right testing method, that corresponds to the actual
parameters set in the activated parameter setting group, is used.
