Conference2This course by Jim Phillips, P.E. has become the industry standard that defines the “Crash Course” in electrical power systems. People from all seven continents (Antarctica included) have attended this week long program that combines five of Jim’s most popular classes including Power System Design 1 & 2, Short Circuit Analysis, Coordination Studies and Power Factor and Power System Harmonic Analysis.  This class is loaded with many in class examples and problems for a hands on learning experience.

Jim has developed this course based on over 35 years of extensive experience with industrial, commercial and utility power systems and standards development.  Jim is currently the Vice-Chair of IEEE 1584 and the International Chair of IEC TC78 Live Working.  Even instructors from other training companies have attended Jim’s classes to see how it’s done. You will learn power system design as well as conduct a short circuit and coordination study and design harmonic filters.

This class also makes a great Professional Engineering Exam Review!
