SESShield-3D is a software package dedicated to the analysis and design of shielding systems against lightning strikes in complex 3D environments.Included Software Tools
SESShield-3D is a powerful software package for the analysis and design of lightning shielding protection systems in complex 3D environments, including substations, power plants, industrial plants and other such installations, accounting for the presence of power lines, equipment, and buildings. SESShield-3D allows arbitrary metallic structures to act as shielding systems, including not only shield wires and masts, but also other structures that attract lightning.
SESShield-3D offers a simple and intuitive graphical user interface that can be used to carry out a complete lightning shielding analysis for a system of freely positioned objects having various geometrical shapes, such as: catenaries, cylinders, cones, cubes and other prisms. Furthermore, calculations are extremely rapid and provide clear, interactive, 3D graphical feedback, so that a shielding system can be designed very quickly and efficiently.
SESShield-3D can analyze and design a lightning shielding system for the protection of vulnerable systems of arbitrary geometries. SESShield-3D can also assess the probability of failure of a lightning protection system, accounting for the statistical distribution of lightning in the area of the system to be protected.
Lightning Shielding Methods
A shielding failure analysis option is also available to determine the rate of shielding failure based on lightning data statistics specified by the user.
The program uses an object-oriented approach to describe the geometry that allows you to select, copy, paste and delete the objects.
The following figures illustrates four shielding methods that can be used in SESShield-3D:
IEEE Std-998 - IEEE Guide for Direct Lightning Stroke Shielding of Substations
IEEE Std-1243 - IEEE Guide for Improving the Lightning Performance of Transmission Lines
 IEC Std-62305-1 Ed. 1.0 - Protection Against Lightning
