Cdegs Cost

[Boyan Atanaschev]

Themost powerful and accurate suite of commercially available grounding (earthing) and electromagnetic analysis software packages on the market. A complete array of auxiliary software tools are included in the CDEGS suite to complement, support and enhance the methods used to solve various problems involving grounding, electromagnetic interference, electromagnetic fields and transient phenomena that can be tackled by CDEGS.

These packages come in many different flavors to provide cost-effective solutions (investments that pay for themselves by preventing overly conservative designs and unnecessary material and labor costs) adapted for problems ranging from simple grounding designs to the behavior of complex networks of aboveground and buried conductors energized by lightning or other transients. Refer to their respective pages for a detailed description of the differences and nuances between them.

It also includes the AutoGroundDesign, AutoGrid Pro and Right-of-Way Pro software packages, which use alternative interfaces to specific combinations of the computation modules that automate specialized tasks in grounding design, grounding analysis and interference studies, respectively. Five specialized packages are also bundled in the CDEGS package: SESShield-3D, SEShield-2D, SESEnviroPlus, SESTLC and CorrCAD. CDEGS is the full suite of software packages SES provides. All future updates, enhancements and additions developed by SES are provided without extra charges to customers that are under our yearly software support.

SES is an internationally recognized R&D pioneer and leader in the areas of power system grounding (earthing) and electromagnetic interference, including transient and lightning analysis. Its CDEGS suite of software packages is the state of the art in this field of expertise and an industry reference worldwide.

A network license can be upgraded with additional concurrent users, and a standalone license can be upgraded to a network license. The fee to upgrade depends on the license being upgraded, and on the number of concurrent users the upgraded license will be valid for. Users interested in learning more about license upgrades may contact&nbspour&nbspsales&nbspteam for details.

Depending on the number of software users and the frequency with which they will use the software, a network license can be a cost-effective option, even when a network license is valid for only one concurrent user.

A network license also provides flexibility, since multiple users may obtain a license, and there is no need for moving a software protection dongle from one workstation to another. Instead, a software protection dongle is connected to a license server, which distributes the licenses to remote users.

When there are multiple concurrent users on a network license, the probability is increased that a license will be available for a given employee at any moment. This is therefore a preferred option for clients with multiple users, especially when one or more employees use the software on a regular basis.

Also, clients with multiple network licenses can install them on different license servers, which can potentially be in different locations. This enhances the availability of the software to the various workstations requesting a license from the first available server. A network license authorizes access through VPN and terminal services.

One of the most revered topics in electrical engineering is electrical earthing. Traditionally electrical earthing systems design has been a specialised field with topic experts and dedicated departments within organisations who are responsible. This has partly been because electrical earthing is both complicated requiring effort to understand and also because it is related to safety.

In terms of safety for humans, assuming an earthing system is designed properly there are significant safeguards and improvements to safety it can provide. Electrical fault currents which are potentially fatal to humans in the form of touch or step voltage hazards are captured by an earthing system and safely directed to and dissipated into the ground.

SafeGrid is a well-known and a complete earthing design software package which has been in the market since 2009. It is one of the few packages world-wide which has multilayer soil modelling capability making it much more accurate than software which can model up to 2 soil layers only.

Note that earthing software that neglects voltage drops in grid conductors can dramatically underestimate earthing requirements near high voltage equipment and overestimate grounding requirements everywhere else.

Multilayer soil modelling for custom grids in 3D. Advanced algorithm suitable for high-frequencies and considers series voltage drops on grid conductors. Several modules included as standard such as fault current distribution and lightning protection. Transient time-domain calculations available.

SES Technologies is a Canadian based company which offers the well-known CDEGS Suite software package combining both earthing and electromagnetic analysis into one program. The software includes accurate circuit analysis calculations that work in tandem with earthing calculations and helps greatly in analysing electromagnetic related problems often encountered in electrical systems. There are many different packages offered by SES for earthing design where CDEGS is the highest package which includes all the capabilities of all of them.

SINT (Italy based) has developed the XGSLab Suite, which includes several modules to assist with grid analysis, incorporating low frequency analysis of grounding systems and soil calculations. It can take input data from graphical files (such as AutoCAD .dxf files) or numerical files, ensuring that it can do calculations from all sorts of data.

Relatively difficult to use and high prices for standard capabilities. Add-ons for fault current distribution (NETS) and lightning protection (SHIELD) cost extra. Technical support provided by a reseller network and not SINT (Italy) directly.

ETAP is well-known and supported software and widely used for power system analysis. Useful package for analysing simple grids of any shape. Up to two soil layers with soil modelling and IEEE safety standards.

Very basic in terms of features and dated software interface. Main algorithm is flawed in that it assumes equipotential grid segment voltages leading to large errors. IEC and EN safety standards not supported. May not be able to purchase the grounding software separately from the entire ETAP suite. Only deals with two layer soils.

SKM has developed the GroundMat software with the purpose of substation ground grid design and analysis. GroundMat specialises in the optimisation of pre-existing grid designs, or reinforcing pre-existing grids, regardless of shape. With the usage of a finite element algorithm, it can validate ground system efficiency with ease.

EATON has developed the CYMGRD software as a means of substation grounding design and analysis, seeking to make not only the design of new grids easier, but to reinforce existing grids to be as efficient and cost effective as possible. With user-friendly data entry and efficient analysis algorithms, the CYMGRD software makes arriving at cost-effective solutions easy.

The CYMGRD software offers the following features:

The Advanced Power Concepts (APC) Integrated Grounding System Analysis for Windows (WinIGS) is a software that performs analysis and design of one or more grounding systems in an electrical power system. It allows the user to analyse the performance under steady state, transient and fault conditions and to evaluate this performance as per several industry-standard criteria.

CDEGS is an advance software which makes the designing and validation of design possible and much easier for us. JMV, being a one-stop solution provider, offers you its services of designing with the help of CDEGS only so that you can ensure that you have got the most practical and cost effective solution for your project.

As per standard IEEE 80, the recommended software for accurate results that provide the desired value for earthing system is named as CDEGS (Current Distribution, Electromagnetic Interference, Grounding and Soil Structure Analysis) software. It provides the touch and step value that prevent from electric shocks, ground rise and potential rise value that eliminate the potential difference that further forbid the current which are approaching towards the ground. This software is inbuilt with eight successive modules that provide precise result in current distribution above and under the ground, lightning protection designing as per IS/IEC 62305, EMI & EMC studies, cathodic current protection. The modules provide the accurate value or result along with the proper soil analysis. The 3-D graphical report generation is also possible while using CDEGS software.

CDEGS is designed on the basis of IEEE 80 and all its modules are complying the standards- IEEE 80, IEEE 998, IEEE 81, IS/IEC 62305. With this remarkable software, the designing can be done as per the real time site data to have the accurate results and solution for the project.

Most of the time when we do the earthing calculations manually through excel sheets, we have to do the calculations on the assumption basis. For instance, we have to take only one soil resistivity of the location so either we select the higher one or we take the average value. Because of which what happens, either we under design the system or we over design the system which increase our project cost unnecessarily. So, to avoid all these scenarios, CDEGS software comes into the role.
