Section 4 Starting up4.1 Factory and site acceptance testingTesting the proper IED operation is carried out at different occasions, for example:• Acceptance testing• Commissioning testing• Maintenance testingThis manual describes the workflow and the steps to carry out the commissioningtesting.Factory acceptance testing (FAT) is typically done to verify that the IED and itscorresponding configuration meet the requirements of the utility or industry. This testis the most complex and in depth, as it is done to familiarize the user with a newproduct or to verify a new configuration. The complexity of this testing depends onseveral factors, such as:• New IED type• New configuration• Modified configurationSite acceptance testing (SAT or commissioning testing) is typically done to verify thatthe installed IED is correctly set and connected to the power system. SAT requires thatthe acceptance testing has been performed and that the application configuration isverified.Maintenance testing is a periodic verification that the IED is healthy and has correctsettings, depending on changes in the power system. There are also other types ofmaintenance testing.4.2 Commissioning checklistBefore starting up commissioning at site, check that the following items are available.• Single line diagram• Protection block diagram• Circuit diagram• Setting list and configuration• RJ-45 Ethernet cable (CAT 5)• Three-phase test kit or other test equipment depending on the complexity of theconfiguration and functions to be tested.1MRK 511 360-UEN A Section 4Starting upBay control REC670 2.1 IEC 41Commissioning manual
