Chapter 5 Commissioning
5.1 General
Commissioning is not considered finalized before a commissioning report has
been made and distributed to all concerned parties (customer and supplier). A
commissioning report is a vital tool for future service, maintenance and trouble
shooting.
NOTE: The commissioning report has to be sent to ABB in order to obtain
future warranty claims.
A recommended commissioning report can be found in
Annex 5. Commissioning
Report.
General safety precautions must be followed during commissioning and
all work has to be performed by qualified personnel.
5.2 Check of mechanical installation
Before commissioning:
1.
Check that the installation and alignment is made acc. to
Chapter 3. Installation and alignment
.
NOTE: The alignment protocol should always be included in the
commissioning report.
2.
Check that the machine is properly fixed to the foundation.
3.
Check for cracks in the foundation and the general condition of the foundation.
4.
Check the tightness of the fixing bolts.
5.
Open the machine, and check that the air-gap is free.
6.
If possible, turn the rotor by hand and make sure that the rotor turns freely and
that there are no abnormal sounds.
7.
Check the assembly of the main terminal box.
8.
Check that all transport locking devices are removed.
5.3 Check of electrical installation
The power cables can be permanently connected to the terminals in the main
terminal box after the stator insulation resistance has been measured, see
Chapter 7.7.4. Insulation resistance measurements for auxiliaries
.
Before commissioning, check the connection of power cables:
1.
Check that the fixing bolts are tightened with the correct torque.
2.
Check that the power cables are suitably routed and do not cause any
additional strain to the terminal bars.
3.
Check that the power cables are correctly stress-relieved.
4.
Check the connections of the auxiliary equipment.
5.
Check the tightness of the cable glands and enclosure sealing.
