Preparing for test

8.1.1

Requirements

IED test requirements:
• Calculated settings
• Application configuration diagram
• Signal matrix (SMT) configuration
• Terminal connection diagram
• Technical manual
• PCM600
The setting and configuration of the IED must be completed before the testing can start.
The terminal diagram, available in the technical reference manual, is a general diagram of the IED.
Therefore, before testing, check that the available terminal diagram corresponds to the IED.
The technical manual contains application and functionality summaries, function blocks, logic
diagrams, input and output signals, setting parameters and technical data sorted per function.
Prepare the IED for test before testing a particular function. Consider the logic diagram of the tested
protection function when performing the test. All included functions in the IED are tested according to
the corresponding test instructions in this chapter. The functions can be tested in any order according
to user preferences. Only the functions that are used (Operation is set to On) should be tested.
The response from a test can be viewed in different ways:
• Binary outputs signals
• A PC with PCM600 application configuration software in work online mode
All setting groups that are used should be tested.

Testing IED operation

Note that the same diagram is not always applicable to each specific delivery (especially
for the configuration of all the binary inputs and outputs).
Consider the configured logic from the function block to the output contacts when
measuring the operate time.
After intense testing, it is important that the IED is not immediately restarted, which might
cause a faulty trip due to flash memory restrictions. Some time must pass before the IED
is restarted. For more information about the flash memory, refer to section "Configuring
the IED and changing settings".
If the IED is used together with a merging unit and no time synchronization is available,
for example, in the laboratory test, the IED will synchronize to the SV data stream. During
the re-synchronization, the protection functions will be blocked once a second for about
45 ms, and this will continue for up to 10 minutes. To avoid this, configure PTP (IEEE
1588) to On for the access point where the merging unit is configured.
