SESShield-2D is used to assess risks associated with lightning strikes to structures and to the services entering those structures. It provides a qualitative and quantitative assessment of risk of loss pertaining to simple structures in accordance with IEC 62305-2.

Included Software Tools


The main purpose of the risk assessment module is to provide a formal assessment of the risk of different types of loss pertaining to vulnerable structures. These risks include damage to the structure itself, to its components and contents, and may also extend to the surroundings of the structure and or even involve the local environment. This type of analysis contributes to the selection of appropriate protection measures for reducing lightning-associated risks to a tolerable level.

Intuitive User Interface

The user interface enables users to specify the characteristics of each analyzed structure, to split projects into multiple zones, and to indicate the services connected to each zone. Computation results are provided in a separate panel, with color-coded plots for easy determination of whether a Calculated Risk for a given risk component is tolerable.


  • Division of structures into multiple zones, assessed individually
  • Consideration of multiple connected services (e.g. power and telecommunication lines)
  • Selection of Risk Components
  • Ground Flash Density (GFD) value can be refined according to regional Keraunic Level
  • Rapid identification of specific risks that require attention
  • Generation of detailed reports

Lightning Shielding Protection for Complex 3D Environments

SESShield-2D is the ideal software tool to conduct risk assesments in accordance with procedures described in IEC 62305-2, however it can not be used to conduct lightning shielding protection studies. Such studies can be carried out with the SESShield-3D software package, which is used to model arbitrary complex 3D systems, design their lightning shielding systems using industry-accepted methods, and to do shielding failure analyses.
