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

Before 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 the configuration
and functions to be tested.
• PC with PCM600 installed along with the connectivity packages corresponding to the IEDs to be
tested.
• Administration rights on the PC, to set up IP addresses
• Product documentation (engineering manual, installation manual, commissioning manual,
operation manual, technical manual and communication protocol manual)

Checking the power supply

Check that the auxiliary supply voltage remains within the permissible input voltage range under all
operating conditions. Check that the polarity is correct before energizing the IED.

Starting up

Do not insert anything else to the female connector but the corresponding male
connector. Inserting anything else (such as a measurement probe) may damage the
female connector and prevent a proper electrical contact between the printed circuit
board and the external wiring connected to the screw terminal block.
