This book instructs the reader on how to size a network’s equipment and address requirements for fast-transient loads (kiloampere loads that last for several minutes). It explores specific calculations used to design equipment for plants. The chapters discuss economic design methods and dynamic-load requirements for electrical equipment. New motor thermal models are developed and power-cable thermal models are also covered. Furthermore, it presents universal plant-load breakdown.


"Bob Henry has used his extensive experience and knowledge to address calculations for electrical engineering in industrial plants. He has shown the calculations for using an uninterruptible power supply to power large motors driven by a variable frequency drive which is the first time I have seen it addressed in a textbook. This is a unique application that having the calculations to size the units and show the operation will be very helpful in operating plants."

David E Nelson, Senior Electrical Engineer

About the Author

Robert E. Henry, PE, has fifty-five years of engineering experience. His early years were in aerospace, designing military electronics and spacecraft. He worked in the Apollo Program in design of the Lunar Module. Most of his experience was spent in electrical power with utilities and engineering companies. He is a graduate electrical engineer, and he holds a Master’s degree in management. His design experience has been with commercial buildings, with power generating plants both in the US and abroad, with transmission substations, with electrical equipment manufacturing, with the food industries, in oil refineries, in mining and metals, in paper production, and in nuclear plant design. He has held the positions of senior engineer, lead engineer, group supervisor, department head, director of engineering, and principal. He retired in 2013 from Bechtel Corp. after eleven years of service. He now has his own consulting company in the Houston area. He was an adjunct professor with Washington State University in the engineering school and with Des Moines Iowa Community College. His publications are in circuit design, in orbital rendezvous and in power engineering with interest in kiloampere loads lasting several minutes. He is a Korean War veteran with the USAF.
