Testing of IEC 61850 Based Protection Systems Notes Dr. Alexander Apostolov

Questions Why are we testing? What are we testing? What should be tested? How it should be tested?

Quality Process

IEC 61850 Testing Requires good understanding of: The functional hierarchy of the IEC 61850 system The local and distributed functions Existing testing tools The purpose of the test: Conformance Type Acceptance Commissioning Maintenance
