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.
This IED is designed for a maximum continuous current of four times
the rated current.
All references to CT and VT must be interpreted as analog values
received from merging units (MU) via IEC/UCA 61850-9-2LE
communication protocol, analog values received from the transformer
input module, or analog values received from the LDCM.
When using a MU test simulator, make sure it is set to the correct SVID
and that the system frequency is set to the same as in the IED.
Please observe the measuring accuracy of the IED, the test equipment
and the angular accuracy for both of them.
Please consider the configured logic from the function block to the
output contacts when measuring the trip 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
