Factory and site acceptance testing
Testing the proper IED operation is carried out at different occasions, for example:
•
Acceptance testing
•
Commissioning testing
•
Maintenance testing
This manual describes the workflow and the steps to carry out the commissioning
testing.
Factory acceptance testing (FAT) is typically done to verify that the IED and
configuration meets the requirements by the utility or industry. This test is the most
complex and in depth, as it is done to familiarize the user to a new protection or to
verify a new configuration. The complexity of this testing depends on several factors.
•
New IED type
•
New configuration
•
Pre-configured
•
Modified existing configuration
Site acceptance testing (SAT or commissioning testing) is typically done to verify
that the new installed IED is correctly set and connected to the power system. SAT
requires that the acceptance testing has been performed and that the application
configuration is verified.
Maintenance testing is a periodical verification that the IED is healthy and has
correct settings depending on changes in the power system. There are also other
types of maintenance testing.
