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 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 PCM600 should be used. PCM600 includes
the Signal monitoring tool, which is useful to read of 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.
The disturbance report settings must be checked to ensure that indications are correct.
Functions to test, signal and parameter names can be found in 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 650 series products 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 the
tests must be repeated 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.
Observe during testing that the right method for testing must be used that
corresponds to the actual parameters set in the activated parameter setting group.
