Commissioning Of
Electrical Systems |
|
The purpose of electric systems commissioning is to
increase the reliability of electrical power systems
after installation by identifying problems and
providing a set of baseline values for comparison with
subsequent routine tests. A procedure should be
developed to include a planned approach (road map) of
what should be done in order to verify the proper
system installation. This procedure is the
commissioning plan. Specific areas addressed in a
commissioning plan include the verification of the
installation of all equipment/components, interface
connections between equipment and individual systems,
and interconnection drawings. The development of this
test plan specific to each system and/or component is
key to the usefulness of any maintenance program.
The plan consists of the schedule of when acceptance
and routine tests should be performed, test forms to be
used to record the outcome of the tests which are
retained for comparison with previous and subsequent
tests, and a listing of the required test devices.
Since the results of the commissioning tests become
baseline test values to compare with later tests and
the results of the routine maintenance tests are
compiled to identify any downward trend in performance,
it is vital to the maintenance program to have accurate
and complete records. To perform the testing, the plan
lists all required tests in order of performance and
gives a schedule for each test. The work items and
schedule depend on many items including the importance
and cost of the equipment, consequences of failure, age
of equipment, past and future frequency of service,
hours of operation, future maintenance availability,
environmental conditions, and safety
requirements.
