Electrical Calculations I

Starts:  Feb 6, 2019 8:00 AM (ET)
Ends:  Feb 7, 2019 4:00 PM (ET)

Who Should Attend:

This two day course is designed for technicians, designers or novice engineers who are new to the power industry and have a very limited background in electrical calculations. Basic awareness of utility electric systems is necessary and attendance of the Power Utility Institute: Overview of the Electrical System course or suitable work experience is a prerequisite.

A background in college-level math and electric circuit theory are recommended. Students must be familiar with using an engineering or scientific calculator and bring one to use in class.

This course or equivalent work experience is a prerequisite for other Power Utility Institute courses, such as the Distribution Protection course.


This course provides a brief review of electric circuit theory, and then covers the basics of AC voltage and current, single-phase and three-phase AC power, real and reactive power, load types, transformers, phasing, trigonometry relationships, polar and rectangular notation and per unit calculations.

Upon completion of this course, participants will have the skills to perform basic AC power calculations and will have a foundation for more advanced courses that deal with analyzing AC circuits and systems.
