World Leader in Grounding Lightning and Electromagnetic Interference
SES primary focus is helping its customers assess and mitigate the effects of grounding & electromagnetic interference on people, equipment and the environment, safely, efficiently and economically.
Since its foundation in 1978, SES has been recognized as an undisputed world authority on the effects of soil on the interaction between electric installations and other utilities such as gas and oil pipelines, communication industries, railway electrification. SES holds the distinction of being the only company worldwide totally dedicated to providing the engineering community with expertise, software and training for the solution of complex problems related to grounding and electromagnetic interference. SES has earned an international reputation for pioneering work in grounding and in electromagnetic and conductive interference analysis involving electrical networks. Typical areas of application for its R&D work include electrical system networks and neighboring utility installations such as oil and gas pipelines, telecommunications cables and railway tracks.
Its leadership is maintained through an aggressive and ongoing R&D program, regular involvement in the analysis of a wide variety of practical and challenging industrial problems, and its support of a superior and growing line of engineering applications software modules
The CDEGS software package (Current Distribution, Electromagnetic Fields, Grounding and Soil Structure Analysis) is a powerful set of integrated engineering software tools designed to accurately analyze problems involving grounding, electromagnetic fields, electromagnetic interference including AC/DC interference mitigation studies and various aspects of cathodic protection and anode bed analysis with a global perspective, starting literally from the ground up. CDEGS computes conductor currents and electromagnetic fields generated by an arbitrary network of energized conductors anywhere above or below ground for normal, fault, lightning and transient conditions. CDEGS models simple and multi-component conductors, including bare, coated pipes and pipe-enclosed cable systems buried in complex soil structures. CDEGS and its subpackages, coupled with toll-free support from the world’s leading R&D design team in these specialties, provide you with an array of cost-effective solutions for problems ranging from simple grounding grid designs to the behavior of complex networks of aboveground and buried conductors energized by lightning or other transients. By providing you with a powerful drawing tool and allowing you to exchange graphical data with AutoCAD and other software supporting DXF, CDEGS makes data entry enjoyable. Flexible data reporting and graphing utilities allow you to collect and illustrate any aspect of the results that are important for your work. Whether you are confronted with a complex grounding design, EMF studies, electromagnetic compatibility and interference problems or a lightning/surge study, you can rely on CDEGS’ accurate, powerful and integrated software components for a realistic, optimized solution.
Extensive scientific validation of the software using field tests and comparisons with analytical or published research results have been conducted for over twenty years. The validation conducted by SES as well as other independent researchers is documented in hundreds of technical papers published in the most reputed international journals.
SES started the development of the CDEGS software package in 1972, with the creation of the MALT engineering module. Since that time, CDEGS has undergone steady growth and refinement. It is composed of eight engineering modules RESAP, MALT, MALZ, TR ALIN, SPLITS, HIFREO, FCDIST,and FFTSES. CDEGS also includes input/output processors and utilities (e.g., import/export to CAD software, text editor).
