# Electrical Design of Overhead Power Transmission Lines

by: Masoud Farzaneh, Ph.D., Shahab Farokhi, Ph.D., William A. Chisholm, Ph.D.

**Abstract:**Electrical Design of Overhead Power Transmission Lines discusses everything electrical engineering students and practicing engineers need to know to effectively design overhead power lines. Co-written by experts in power engineering, this detailed guide addresses component selection and design, current IEEE standards, load-flow analysis, power system stability, statistical risk management of weather-related overhead line failures, insulation, thermal rating, and other essential topics. Clear learning objectives and worked examples that apply theoretical results to real-world problems are included in this practical resource. Electrical Design of Overhead Power Transmission Lines covers: • AC circuits and sequence circuits of power networks • Matrix methods in AC power system analysis • Overhead transmission line parameters • Modeling of transmission lines • AC power-flow analysis using iterative methods • Symmetrical and unsymmetrical faults • Control of voltage and power flow • Stability in AC networks • High-voltage direct current (HVDC) transmission • Corona and electric field effects of transmission lines • Lightning performance of transmission lines • Coordination of transmission line insulation • Ampacity of overhead line conductors
