Testing the protection functionality

Each protection function must be tested individually by secondary injection.
• Verify operating levels (trip) and timers.
• Verify alarm and blocking signals.
• Use the disturbance handling tool in PCM600 to evaluate that the protection function has received
the correct data and responded correctly (signaling and timing).
• Use the event viewer tool in PCM600 to check that only expected events have occurred.

If the IEC/UCA 61850-9-2LE communication is interrupted during current injection, the
disturbance report tool in PCM600 will display the current that was injected before the
interruption.
