Section 8 Commissioning
8.1 Commissioning checklist
Familiarize yourself with the protection relay and its functionality before you start the
commissioning work.
• Ensure that you have all the needed station drawings such as single line and
wiring diagrams.
• Ensure that your version of the technical manual applies to the protection relay
version you test.
• Ensure that your setting software and connectivity packages work with the
protection relay version you test.
• Find out if you need any additional software.
• Ensure that you have the relay settings either on paper or in electronic format. The
settings and logic should be well documented.
• Inspect the settings to ensure that they are correct.
• Ensure that you have the correct cable to connect your PC to the protection relay's
communication port. The RJ-45 port supports any CAT 5 Ethernet cable but the
recommendation is STP.
• Test your PC's communication port before you go to the site.
• Find out who to contact if you have trouble and make sure you have a means to
contact them.
• Find out who is responsible for the settings.
• Ensure that you have with you the proper test equipment and all needed
connection cables.
• Ensure that the owner of the switchgear familiarizes you with the work site and
any special aspects of it.
• Ensure that you know how to operate in emergency situations. Find out where the
first aid and safety materials and exit routes are.
