10.7 Testing the protection functionality
GUID-125B6F28-D3E5-4535-9CD6-6C056B79F496 v2
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.
