IEEE 2771-2021 IEEE Guide for Parameter Configuration of Arcing Horns of DC Earth Electrode Lines

standard by IEEE, 01/20/2022

Full Description

Scope

This guide indicates the configuration parameters for arcing horns of direct current (dc) earth electrode lines, including sustained dc arc current, composition, installation, and gap distance of arcing horns. This guide applies to the configuration of arcing horns of dc earth electrode lines (hereafter referred to as arcing horns) for new or reconstructed dc transmission projects.

Purpose

This guide indicates the dimension, installed position, and gap distance of arcing horns of earth electrode lines, and provides a criterion for the configuration of arcing horns of dc earth electrode lines, which increases the safety and stability of dc transmission systems.

Abstract

New IEEE Standard - Active.Operating voltage, overvoltage, and sustained dc arc current of dc earth electrode lines are introduced in this guide. Technical conditions of arcing horns are discussed, including gap spacing, structures, materials, and layout. In addition, tests for arcing horns are recommended.
