Guide for Direct Lightning Stroke Shielding of Substations

This guide describes the general nature of lightning and discusses design methods for placement of masts and shield wires to provide direct stroke shielding of outdoor substations.Tables, formulas, and examples are provided to calculate effective shielding from direct lightning strokes. This guide specifically does not include: 1) every shielding design method that may have been developed 2) protection from surges entering a substation over power or communication lines 3) personnel safety issues

998-2012

IEEE Guide for Direct Lightning Stroke Shielding of Substations

Design information for the methods historically and typically applied by substation designers to reduce direct lightning strokes to equipment and buswork within substations is provided. Two approaches, the classical empirical method and the electrogeometric model, are presented in detail. A third approach, which involves the use of non-conventional lightning terminals and related design methods, is also reviewed.

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


998-1996

IEEE Guide for Direct Lightning Stroke Shielding of Substations

Design information for the methods historically and typically applied by substation designers to minimize direct lightning strokes to equipment and buswork within substations is provided. Two approaches, the classical empirical method and the electrogeometric model, are presented in detail. A third approach involving the use of active lightning terminals is also briefly reviewed.

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
