Review
Picture of Farid Over the last year, SES has gone through considerable restructuring of its approach to software development, making it faster and more flexible. This has allowed us to deliver, more quickly, the features that our users want. This restructuring has also provided for the greater reliability in our software products demanded by our users. .....more

CDEGS New Features
CDEGS Logo Plots of touch and step voltages for large irregular shapes can be created easily and quickly. When studying large or sparse grids, users can create a perimeter profile a specified distance around the precise area of interest. From this, produce visually enhanced representations of the touch and step voltages. .....more

Towards The Future: Introducing TLC from SES
Towards the future A Transmission and Distribution Line Calculator for Rapid EMF, Line Parameter, and Induced Voltage Estimates line
The new TLC software package is a simplified analysis tool that quickly estimates line parameters, electric fields, and magnetic fields associated with arbitrary configurations of parallel transmission and distribution electric lines. It also estimates induced voltages and currents on other parallel metallic utilities, such as pipelines and railways. It has been designed with simplicity in mind, providing much useful information with minimal data entry; it is analogous to SESGSE, the Grounding System Estimator developed for the estimation of grounding requirements. TLC features new transmission & distribution line structure databases coupled with databases containing an extensive library of conductors, including rails and pipelines. These databases, together with the intuitive user interface, provide an efficient tool that can be applied directly to simple system configurations; this can be helpful for preliminary analyses of more complex systems. For more complex systems or more detailed studies, SES recommends the Right-Of-Way or HIFREQ software. .....more

Analysis of grounding systems in soils with finite volumes of different resistivities.
J. Ma and F. P. Dawalibi
Abstract: A theoretical model for the analysis of grounding systems located in soils with finite volumes of arbitrary resistivities is presented. The boundary element method is used for the analysis. The procedures in the analysis are described in detail and the essential equations are presented. Analytical and numerical validations are also carried out in the process. The results obtained using the new approach are in agreement with well-known simple case results and converge asymptotically to the uniform soil case. There is a wide range of practical grounding system scenarios which can be accurately modeled by using this new soil type. Examples showing several finite volume soil models are also presented.
