Section 10 Testing IED operation
10.1 Preparing for test
IP336-1 v1
10.1.1 Requirements
M11740-2 v11
IED test requirements:
• Calculated settings
• Application configuration diagram
• Signal matrix (SMT) configuration
• Terminal connection diagram
• Technical manual
• Three-phase test equipment
• Process bus, IEC/UCA 61850-9-2LE, MU test simulator, if IEC/UCA 61850-9-2LE process bus
communication is used.
• 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.
Note that the same diagram is not always applicable to each specific delivery (especially
for the configuration of all the binary inputs and outputs).
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.
The test equipment should be able to provide a three-phase supply of voltages and currents. The
magnitude of voltage and current as well as the phase angle between voltage and current must be
variable. The voltages and currents from the test equipment must be obtained from the same source and
they must have minimal harmonic content. If the test equipment cannot indicate the phase angle, a
separate phase-angle measuring instrument is necessary.
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 Enabled) should be tested.
The response from a test can be viewed in different ways:
• Binary outputs signals
• Service values on the local HMI (logical signals or phasors)
• A PC with PCM600 application configuration software in work online mode
All setting groups that are used should be tested.
