About the Class

Course Description

This course covers the principles of DC (Direct Current) electricity in a simple, easy-to-understand, format. It is themed after a book published by the instructor, titled: “Electrical Engineering for non-Electrical Engineers.” In the book, as well as this seminar, Rauf uses simple analogies and practical, day-to-day, examples to illustrate the, otherwise, abstract concepts of DC electricity. Upon attending this course, participants will be able to perform straightforward and common calculations, in the DC realm, associated with voltage, current, resistance, circuit analysis, power, service factor, and much more. Practical examples of DC electrical equipment applications, in industrial, and institutional settings are covered. This includes discussion on DC power transmission systems, solar PV systems, EV’s (Electric Vehicles), LED’s, DC ESS (Energy Storage Systems), HESS, DC-DC converters, DC mining dragline equipment, Diesel locomotives, etc. Applications of electronic DC safety devices are explained and illustrated. A few DC articles in the National Electrical Code are introduced. This course is designed for engineers, professional engineers, energy professionals, engineering managers, technical professionals, facilities managers, and other professionals who are not intimately familiar with DC principles, practices, and applications. The audience is engaged through QA; classwork, and ad hoc discussions pertaining to the topic.

What will you learn in this live class?

  • After attending this course, you will know the principles and concepts associated with DC electricity and the distinction between DC and AC electricity. This understanding can be used to apply appropriate mathematics and physics-premised techniques, principles, and equations for analyzing DC systems, in electronics and electrical power domains.
  • You will learn about the differences between DC and AC power transmission systems.
  • You will learn about DC-based electrical energy production (PV) and Energy Storage Systems i.e., batteries and supercapacitors.
  • You will get introduced to myriad DC technologies and equipment and gain an appreciation of how ubiquitous and indispensable DC is in our personal and professional lives.
  • You gain familiarity with DC power distribution equipment and instrumentation.
  • You will understand the role NEC, and NFPA 70 E, play in the realm of DC electrical design, electrical safety, and arc flash hazard.
  • You will learn how to interpret DC electrical one-line and control diagrams.

Why you shouldn’t miss this course – How this course can benefit you, your organizations, and what is unique about this course:

  • Have you ever felt somewhat inadequate and ill-equipped in your technical discussions with electrical engineers and electricians on the topic of DC electricity? If so, then this course or seminar is a must.
  • Do you, as an engineer, manager, or technician, feel that your knowledge and understanding of the difference between AC and DC electricity is inadequate or insufficient, then you must not miss this seminar.
  • How often do you get a chance to attend a workshop, course, or seminar that is presented by the author of the book on the subject matter - live? In this seminar, you will have the opportunity to interact and learn from Bobby Rauf, the author of the text, titled, “Electrical Engineering for Non-Electrical Engineers.” (A copy of the book is available at additional cost)
  • As an engineer, technician, or manager have you ever found the concepts of voltage, current, power, capacitance, inductance, DC motors, DC power transmission, and distribution elusive and hard to comprehend? Then, this seminar will present an excellent opportunity to remedy that.
  • Imagine yourself, as an engineer or manager, at 2 o'clock in the morning, in a triage situation, leading a team, trying to get electrical equipment up and running. You and your team members have electrical drawings of different types spread out, but, without the electrical engineering background, the symbol and nomenclature appear foreign to you. This seminar is an opportunity for you to bridge that gap.
  • How often do you get an opportunity to understand abstract and complex electrical concepts through relatively simple analogies and explanations? This seminar will provide you with that invaluable opportunity.
  • Some workshops and seminars end up being monotonous monologues from the presenter to the audience. Not this one. In this seminar, you will get an opportunity to exercise the skills and concepts through classwork and engage the instructor in discussions.
  • Do you manage or work with electrical engineers or electricians, and are rusty in DC electrical engineering concepts, analytical techniques, and design considerations, or are completely unfamiliar with them? This seminar provides you the opportunity to brush up on that knowledge and skills so that you can understand the challenges confronted by your subordinates and colleagues more clearly and can make informed decisions.

Who should take this live class?

  • Licensed Professional Engineers, who need to meet the annual or biennial license renewal PDH (Professional Development Hour) or CEU (Continuing Education Units) requirements.
  • Engineers and Architects who do not possess current working knowledge of DC electricity and DC electrical equipment.
  • Facility Managers, Engineering Managers, Program/Project Managers, and other executives or leaders who sense a lack of adequate electrical knowledge related to DC and DC-based electrical equipment and therefore feel reluctant in holding meaningful discussions and making informed decisions when interacting with their electrical subordinates or colleagues.
  • Non-engineers, including technical writers responsible for developing operations and maintenance manuals for DC equipment.
  • Procurement/purchasing professionals who are responsible for the acquisition of DC electrical equipment.
  • Energy Managers and Construction Managers.
  • Maintenance Engineers and Maintenance Managers.
  • Other professionals whose annual PLP, Performance and Learning Program, includes engineering/technical courses/seminars/workshops.
