Power System Design Fundamentals for Electrical Engineers - E-41
About the Course
This course is targeted towards early career electrical engineers in the oil and gas industry.
It has been developed through a collaboration with PetroSkills Alliance member Shell Global and is focused on getting electrical engineers up to speed with the essential principles of electrical safety, power system design, studies, protection and equipment specification as well as operations support and maintenance. Additionally, this course introduces the participants to the critical elements of industry and typical company standards as well common project execution and project assurance principles.
The course focuses on foundational concepts rather than regional code and standard requirements, but does address the typical equipment, requirements and methods used in both international (IEC, EN, BS, etc.) and North American (NEC, IEEE) standards related to design and safe operation.
This intensive program is typically held over 10, 8-hour sessions in two weeks, and has been designed to be delivered virtually or in-person. As such, the expectation is that participants to fully engage online, ask and answer questions posed in the course and participate in meaningful discussions related to the concepts, implications and application of the concepts. A sample project will be completed in phases throughout the course, giving the participants an opportunity to work with their peers in solving typical design challenges and applying concepts. Off-line time will be allotted prior to, during and after the course to allow participants to complete assignments at their own pace.
At the end of the course the participants will complete a formal written final exam.
This course has been designed for Electrical Engineers with a bachelor’s or master’s degree (or equivalent) in electrical engineering and 1-3 years’ experience on the job and Senior Electrical and Instrument Technicians or Supervisor whose activities include work on electrical equipment in refineries, gas and chemical plants or oil field installations.
It is assumed that participants will come to the course with academic background in the fundamentals of AC and DC electricity, 3 phase power systems, basic electrical mathematic principles (Ohm’s Law, Kirchhoff’s laws, etc.), phasor math, basic understanding of the role of common industrial power system equipment and components (Substations, Generators, transformers, switchgear, protective devices, cables, conduit, etc.).
Basic knowledge of locating Company and Industry standards is expected.
It is beneficial if students have some practical experience working in industrial facilities so that they can understand the context of the material presented.
This course will be held in English. Participants should be fluent in English with proficiency such that they can participate in technical discussions.
