SWEMA Supplemental Metering Math Course

SWEMA’s Supplemental Math Course 1 is designed for those new to metering or who are seeking to refresh their algebra and trigonometry skills and develop an understanding of the core concepts related to electric theory. The course provides a review of algebra essentials; use of order of operations, strategies for simplifying and solving equations, and reinforcing core concepts related to finding algebraic solutions.  In addition to algebra, the course focuses heavily on developing proficiency with right triangle trigonometry with a specific focus on application to the power triangle and a student’s ability to calculate and determine kVA, kW, kVAr, and Power Factor.  Students’ problem-solving skills are further challenged as they are taught how to apply Ohm’s Law, Kirchoff’s Voltage Law, and Kirchoff’s Current Law through the process of DC Circuit analysis.  Lastly, the course offers a discussion of the foundations of AC Theory to include; Faraday’s Law, power factor, understanding wave forms, basic calculations of inductive and capacitive reactance, and complex impedance.  Overall, students are challenged to exercise their problem-solving skills: understanding the challenge faced, apply their understanding of mathematics and electrical theory, identifying the knowns and unknowns, selecting the right tool to achieve their goal, and methods for checking their answers. Students who complete Course 1 are prepared with an understanding of algebra, trig, the power triangle, and the fundamentals of electric theory necessary to be successful in Course 2 which dives deeper and more practically into applied meter math.
