Electrical Commissioning Checklists
The acceptance testing and
subsequent commissioning of is a critical and important step in the start of
any electrical system, regardless of the size of the system or project. A lack
of experience in handling this process or poor planning and execution can lead
to avoidable delays and compromise security of personnel, which can cause
potential productivity losses or adversely impact the credibility and
reputation of project management function, all of which can have costly
financial implications. Acceptance testing and commissioning of electrical
systems is an elaborate and tedious process that has to be carried out very
diligently and with extreme caution (given the nature of job). To facilitate
the above, an electrical commissioning checklist can be used, which is an
easily referenced list of to-do activities that can act as a handy and
practical tool for ensuring completion of the work, as desired.
Electrical Commissioning Checklists
General Checks
General checks before
commissioning a system include ensuring that all related electrical works are
complete; staff and all the maintenance personnel are adequately informed and
trained in operating and security measures; all fire safety precautions have
been taken; and that emergency procedures are well documented and understood by
required staff.
Electrical Checks
As regards the electrical
appliances and systems deployed, it is prudent to ensure that all required
electrical safety guidelines have been followed; that sufficient precautions
have been taken to avoid exposing to conducting liquids; all subsystems and
appliances operate as expected (are not faulty or have electrical leakage);
high voltage equipment is adequately labeled; that all circuit breakers are
installed and inspected; and that accessibility is sufficiently restricted but
easily available through facilities management when required and as applicable.
Further checks should ascertain
that the electrical power leads are protected from strain or physical damage;
working areas are free from un-insulated cabling or tripping hazards because of
unattended, loose or coiled wiring; and that the power boards have overload
protection and proper grounding. Checks on power points should be done for
determining that they are easily locatable and not obstructed in any manner;
are properly labeled and in good condition; total power load within prescribed
limits; that the high current items are not plugged onto power boards (they
should rather be directly plugged into power points); and that the permanent appliances
have their own dedicated power points.
Outside Checks
Outdoor checks should ensure that
safety procedures are in place for working near overhead power lines; that the
site is suitable for the electrical system installation and operation; and that
only heavy duty power leads are used.
