Participants in this course will be offered comprehensive and crucial guidelines to understanding elements and procedures involved in the commissioning and start up of electrical apparatus and systems involved in major industrial and commercial projects. The course addresses the special problems that may be encountered in the starting up of any electrical system for the first time, which, regardless of size, type or industry, is a special event. Fundamental to the commissioning task is the significant effort required to test each individual apparatus to ensure its proper functioning and its ability to offer service continuity under the specific operating conditions required by the industrial environment. A good deal of time will be spent discussing practical aspects of testing major equipment such as cables, motors, transformers and switchgear. The course will highlight testing procedures, standard testing frequencies, what to expect in the results of testing and remedial actions. The importance of maintenance to maintain design life expectancy can not be overemphasized and the course will offer details of philosophies underlying maintenance practices. This course deals with safety considerations and testing and start-up procedures for all the components of any electrical system. The course will provide useful guidelines on what to do when things go wrong during this phase of a project.
To provide a comprehensive understanding of principles of accomplishing a successful commissioning and start up including testing and subsequent maintenance of the electrical system.
Electrical professionals who need to refresh and expand their knowledge, maintenance managers, and power system consultants. A basic understanding of electrical system operations is needed, but participant do not necessarily have to be experts in the areas covered. In addition, professionals who are starting their career in the field of power in electrical utilities, industrial or commercial and institutional facilities will profit from this course.
