Models for Design: Electrical Calculations for Industrial Plants

Summary

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.
