Design of Electric Power Systems
Jim has developed this course based on over 40 years of extensive experience with industrial, commercial and utility power systems and standards development. He is not just another trainer reading a script. Jim’s training is based on his insider’s view from being very active with many different standards committees which provides him with the unique perspective, literally from the inside. Coupled with his broad electrical power background, he loves sharing his experience and insider’s view with others. 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.
