AC Electricity Principles, Practice, and Applications - 4 PDHs
Webinar / Cost: $165 member; $185 non-member / 9:00am-1:00pm, ET
September 26, 2022

NYSSPE has partnered with Sem-Train, LLC -  New York State Approved Sponsor


This seminar or course covers principles of AC 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 AC electrical engineering. Upon attending this course, participants will be able to perform straightforward and common calculations involving voltage, current, resistance, circuit analysis, single phase AC, three phase AC, power, power factor, service factor, load factor, etc. Practical examples of AC electrical equipment applications, in industrial, commercial, and residential settings are covered.

 

This includes utilization of AC in small to large HVAC systems and air compressors, role of AC in EV’s, AC power transmission, AC power distribution, VFD’s, etc. Participants get introduced, briefly, to single phase and three phase AC electrical drawings. A brief introduction is provided to the National Electrical Code and the ARC Flash Code. This course is designed for engineers, professional engineers, energy professionals, engineering managers, technical professionals, facilities managers and other professionals who are not intimately familiar or current on AC electrical engineering principles and practices. No prerequisite required. The course starts from the basics.

Learning Objectives & Take-Aways

 

1.   After attending this course, you will know the principles and concepts associated with AC electricity. This understanding can be used to apply appropriate mathematics and physics concepts, principles and equations for analysing AC systems.

 

2.   You will know the role played by voltage and current angles in the determination of power factor. The science and engineering theory behind power factor is illustrated using the vector method, graphical representation of voltage and current as a function of time and angle. Participants learn to apply different methods for calculating leading and lagging power factors.

 

3.   You will be able to apply important electrical system concepts, such as, power quality, load factor and service factor, demand, peak demand, distinction between electrical energy and electrical power, and associated engineering computation formulas and methods.

 

4.   You will know the difference between three-phase AC, “Y” and “∆ - Delta” configuration of loads and sources, and know the significance of these configurations from practical power distribution and application perspective.

 

5.   You gain familiarity with power distribution equipment and instrumentation.

 

6.   You will understand the role NEC, and NFPA 70 E, play in the realm of electrical design, electrical safety and arc flash hazard.

 

7.   You will learn how to interpret AC electrical one-line and comprehensive wiring diagrams. 

8.  You will understand how electrical power bills are calculated under large industrial and commercial contract scenarios.
