Course Highlights

This continuing education online PDH course is NY approved. This course is also accepted in the States of AK, AL, AR, DE, FL, GA, IA, ID, IL, IN, KS, KY, LA, MD, ME, MI, MN, MO, MS, MT, NC, ND, NE, NH, NJ, NM, NV, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WI, WV and WY.

This course presents an overview of modern practices in raising efficiency of power systems through application of reactive power and voltage regulation.


It starts with discussion about the structure of power systems from a power plant to the customer, and typical power system voltages in different parts of the system. Then, it explains how power losses and voltage drops in the power system may be reduced through compensation of reactive power either by shunt capacitors for an inductive load or shunt reactors for a capacitive load. Arrangement of a shunt capacitor bank and a sequence of its design is considered as well. Explanations are supported by numerous drawings, photos of actual equipment and the example showing how to design a 230 kV shunt capacitor bank. Finally, it discusses reasons for voltage regulation in power systems and means to perform.  Explanations are supported by photos and example showing how transformer winding taps may be selected.


This online PDH course is applicable to power industry engineers and designers as well as colleges and universities faculty involved with either practical application of reactive power and voltage regulation or teaching its concepts.


In this course, you need to review the course document titled, “Fundamentals of Reactive Power and Voltage Regulation in Power Systems” and provided below. Once you complete your course review, you need to take a multiple choice quiz consisting of twenty (20) questions to earn 3 PDH credits. The quiz will be based on the content of the course document.
