Standard Details
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.

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

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.
