This Guide covers all factors affecting the lightning flashover rate of overhead transmission lines with a phase-to-phase voltage exceeding 38 kV, and an average conductor height exceeding 10 m. These factors include, but are not limited to, lightning activity and stroke characteristics, the stroke attachment process, soil characteristics, insulation strength, line surge arresters, traveling wave analysis, corona, pre-discharge, overhead shield wires, shielding from nearby objects, induced voltages from nearby strokes, and reducing the impact of a flashover. Tower and pole electrical characteristics and grounding methods are addressed. Both AC and DC transmission lines are addressed. The scope excludes medium-voltage distribution lines and low-voltage secondary circuits. Lightning effects on substations, underground cables, and utilization facilities are also excluded. This guide does not explain or evaluate theoretical methods, but to provide guidance for their practical use in line design.
1410-2010 - IEEE Guide for Improving the Lightning Performance of Electric Power Overhead Distribution Lines
Factors that contribute to lightning-caused faults on the line insulation of overhead distribution lines and suggested improvements to existing and new constructions are identified in this guide.
