Electrical Engineering Course II

AC Electrical Systems, Contrast Between AC and DC Systems, AC to DC Conversion, Transformers, Voltage Regulation and Energy Transformation between Electrical and Mechanical Systems – 10 PDH

Engineering Principles and Practice for Non-Electrical Engineers Series



In this 10 PDH course, you’ll learn and get introduced to…

  • AC Circuits, polar and rectangular representation of alternating current (AC) voltage, current, impedance and power.
  • Comparison of DC and AC, and their graphical representation.
  • Concept of average value of AC and associated computation.
  • Electro-deposition and the AC to DC transformation.
  • Introduction to transformers; ideal vs. real transformers, single phase versus three phase transformers.
  • Four transformer configurations of three phase transformers.
  • Various types of transformers and their applications: Isolation transformers, auto transformers, current transformers.
  • Voltage regulation and voltage regulating transformers.
  • Single phase and three phase AC power.
  • Concept of power factor, power factor computation and economic analysis associated with power correction measures.
  • Power and energy flow from “steam to wire,” “water to wire” and “wire to water”.


This seminar introduces the reader to single phase AC, differences between AC and DC, AC applications, complex math based representation of AC circuits and associated circuit analysis. Introduction to three phase AC and three phase AC transformers in simple, easy to understand, format.

Introduction to the concept of power in the DC and AC realms. Comparison of DC and AC power. Examples of power in practical applications and associated computations.

Explanation of the concept of power factor on the basis of vectors, voltage and current graphs, power and apparent power. Impact of power factor on overall power quality, energy productivity, energy cost, mean time between failures and the kVA demand.

Cross-discipline analogies are borrowed–where appropriate -from mechanical, hydraulics and civil engineering
disciplines, to better illustrate the fundamental concepts of electrical engineering. This seminar caters to engineers of all disciplines, as well as technicians, facilities managers and executives who are not intimately familiar with electrical engineering principles and practices. The seminar is based on the principles in the book
Electrical Engineering for Non-Electrical Engineers, S. Bobby Rauf, Fairmont Press, 2013.
