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 its
corresponding configuration meet the requirements of the utility or industry. This test
is the most complex and in depth, as it is done to familiarize the user with a new
product or to verify a new configuration. The complexity of this testing depends on
several factors, such as:
• New IED type
• New configuration
• Modified configuration
Site acceptance testing (SAT or commissioning testing) is typically done to verify that
the 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 periodic 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.

Commissioning checklist
