Venue:           London, United Kingdom
Fee:               $6,500

In any of the 5 star hotels. The exact venue will be informed once finalized.

Operation and maintenance of electric power equipment to assure that the equipment and systems will operate as intended. Periodic maintenance inspections and tests should be conducted on existing electric power equipment to maintain reliability, to reduce major
repair costs, and to trigger need-based maintenance activities. The course describes how equipment operates and how it fails, what inspections and tests should be conducted, and how inspection and test results are evaluated. It also includes developing commissioning
procedures and checklists, and developing maintenance programs. Transformers, circuit breakers, buses, motors, relays and other equipment found in substations, electrical rooms, motor control centers, and panel boards will be discussed.

This will ensure the electrical equipment operates correctly so that production is maximized in a safe, cost effective and efficient manner.

Delegates are encouraged to raise queries both during and at any time after attending the course and are also asked to bring with them any technical issues that they may have.

Objective

Following the attendance at this course, participants will return to their respective organizations equipped with new or refreshed skills to ensure that each power components related to the industrial substations are tested and maintained in a fashion that ensures reduced costs and or start-up delays plus identified faults or problems are repaired and the underlying causes are identified and eliminated to reduce further failures.

Audience

This course is intended for Electrical Engineers, Electrical Supervisors and Electrical Technicians engaged in the commissioning, testing, start-up, troubleshooting, maintenance and repair of Electrical Equipment and Control Systems. Because the methods and examples are generic, trainee from all industries especially oil and gas fields will benefit. Participants need no specific requirements other than good understanding of electricity and magnetism and some relevant experience.
