Overview

Understand the fundamentals of electrical power systems with this accessible guide Few subjects are more fundamental to modern life than electrical power. The systems that generate, transport, and distribute electricity are among the most essential contributors to modern industry, development, and everyday living. As energy demand grows and, with it, the electric power industry, more and more non-electrical professionals must make important policy and administrative decisions regarding the systems that power our world. Electric Power System Basics for the Nonelectrical Professional provides an education on the basics of this subject, including the various types of energy sources, types of transmission and distribution lines, grid modernization, and much more. From residential to industrial energy, and from metering principles to energy conservation techniques, this book provides a one-stop reference on all relevant areas of knowledge. Now fully updated to reflect the latest advances and the current state of a growing industry, it is a must-own for anyone looking to bring foundational power systems knowledge to bear on policy or industrial issues. Readers of the third edition will also find: Coverage of wildfire mitigation strategies to reduce safety risk Detailed discussion of regulatory changes and their effects on system operations Updated coverage of system reliability and smart technologies Updated discussion of the transitioning digital power grid Electric Power System Basics for the Nonelectrical Professional is ideal for power industry executives and state regulators.
