SES Software 2006-2007
Version 13.2.32
Safe Engineering Services & technologies limited
December 2007
This is an update of SES Software 2006, Version 13.0.2; the software enhancements contained in this update are listed below.
Since this is a full installation, an existing version of SES Software 2006 is not required to be installed prior to installing this update.
Installation Instructions
1. Please close all SES software programs prior to installing this update.
2. Run the self-extracting executable, "SESSoft13232.exe", from the path where the executable was downloaded.
3. Click on the Next button to extract the contents of this self-extracting executable to a temporary folder (do not extract to the SES software installation folder). You may define a temporary folder (e.g., C:\Temp\SESSoft13232) that is easy to access since you may have to browse to that folder after the extraction process has completed.
4. Click on the Next button to proceed with the extraction process.
5. The installation will automatically start after the extraction has been completed; please proceed with the on-screen instructions. Note that since this is a full installation, the installer may request to uninstall any existing version of SES Software that it has detected. Please allow the installer to automatically uninstall all of the detected SES Software products before continuing with the installation.
(If the installation does not start automatically, then execute the Setup.exe file manually, from the folder specified in Step 3, to start the installation process).
6. Once the installation has completed, you may delete the temporary folder specified in Step 3.
SES Software Enhancements since Version 13.1.61 Update
The following enhancements have been made in this updated version of SES Software 2006 since the last official update (July 2007) of the software:
Multilayer Soil in TRALIN (Group Mode)
A multilayer soil model is now available when using Group mode in TRALIN. This new model can accommodate any number of horizontal soil layers with different characteristics. It can be used for both buried and overhead conductors, and provides a good estimate of the leakage impedance of buried conductors.
RESAP: Unipolar Measurement Method
The RESAP program now provides direct support for the ‘Unipolar’ measurement method. The input modules of CDEGS, AutoGrid Pro and AutoGroundDesign were updated to simplify the specification of data measured using the Unipolar method. Also, the plotting programs can now produce plots of the measurements as a function of any specified pin spacing, and the plots can now include a line chart of the soil model deduced by RESAP from the measurements.
Another measurement method, the dipole-dipole method, was also introduced in the program.
Improvements in Right-Of-Way – Total Interference
In the Total Interference module of Right-Of-Way, you can now select the conductors to export on the basis of phase number. Also, a new ‘2 Rods (H Frame)’ Grounding Configuration is available, and you can specify the radius of the rods for all types of grounding configurations.
FFTSES Improvements
· The time-domain animation plots produced by the FFT21Data utility for FFTSES can now be saved to disk in AVI format.
· The program can now analyze the Ground Potential Difference (GPD) between selected conductors and a reference conductor.
New Plotting Options for Magnetic Fields in SESTLC
When running in Electric & Magnetic Fields mode, SESTLC can now produce plots of the magnetic field and of the magnetic flux density in most commonly used units.
Improvements to “Raw Data” report in Output Toolbox
When using the raw data report in Output Toolbox to export data from a computation database, you can now control the order of the data and export only the top N or bottom N data rows. Also, you can append the data to an existing file instead of creating a new file.
Plotting as a Function of Distance in SPLITS
It is now possible to use physical distance instead of section numbers to label the X axis when creating plots in SPLITS. This is especially useful when creating a “Regular Plot” in Right-of-Way.
SES Software Enhancements in Version 13.1.61 Update
The following enhancements are also available in this update. Note that they were already present in the last official update of the software, although not in the official release of last year.
New Risk Analysis Module and Back Flashover Analysis in SES-Shield
A new module was added in SES’ Lightning Shielding program (SES-Shield). This new module allows you to assess the risks related to lightning strikes on a structure. The risks include damage to the structure itself, its components and contents, and may also extend to the surroundings of the structure and even involve the local environment. This type of analysis can help in selecting the appropriate protection measures that brings down the risks associated to lightning to a tolerable level.
New “Jagged Victim Line” Option in SESTLC
When calculating ac interference effects under fault or steady-state conditions in SESTLC, the victim line is no longer restricted to be parallel to the transmission lines. With this enhancement, SESTLC can now be used to quickly obtain reliable estimates of the magnitude of ac interference effects in realistic cases. Also, the program now produces plots of the semi-major axis of the electric and magnetic fields when running in Electric & Magnetic Fields mode.
Finite Volume Soil Model: Acceleration of Calculations and Improved Accuracy
The accuracy of the calculations in the finite volume soil model was improved through the introduction of new analytical methods to handle the computations involving patches. These new methods also helped improved the calculation speed of this soil model considerably.
Resistivity of Dry Soils in SoilModelManager
The variation of the resistivity of the soil caused by seasonal changes in soil moisture content can now be estimated using the SoilModelManager utility.
SESCAD: “Generate Paths” and “Combine Paths” Tools
Two new tools were added in SESCAD (Tools | Generate Paths and Tools | Combine Paths) to help identify connected paths among selected conductors. Also, the program now automatically updates the conductor numbers after every editing operation in such a way that the displayed conductor numbers always reflect the order of the conductors in the saved file.
Improvements in RightOfWay
A large number of improvements were introduced in the RightOfWay package. Among those:
· In the Build Network System module, the conductor shunt (ground) impedances and their coating characteristics are now modeled more accurately.
· In the Modify Circuit module, you can now insert or replace connection impedances and shunt impedances by a value specified per unit length of the section.
· It is now possible to specify and compute the GPD (Ground Potential Difference) for multiple points along a line in the Monitor Fault module. Also, several options were added to better control the generation of envelope curves.
· The Total Interference MALZ file created by RightOfWay is now more compact. Also, you can now restrict the calculation of touch voltages to selected conductors, and a new tool was introduced to automatically produce Excel charts of envelope curves.
Visualizing Results while Running an Engineering Program in CDEGS Integrated Mode
In CDEGS – Integrated Mode, it is now possible to edit the input data or visualize the results of one job while running another. This feature is subject to the same restriction as in Classic Mode, namely that at least one of the Job ID or Working Directory of the two cases must be different.
Note:
This version also includes a fix for the following problem found in the version of the software distributed at the 2007 CDEGS Users Group Meeting:
· In CDEGS – Specify (Input Toolbox) for MALZ, the soil data was incorrectly displayed when loading the Soil-Type screen.
